2011-01-04 Tag 1.0.1 for release at r8897 2010-11-22 Fixed error with Hammer projection. - BVR 2010-11-12 Fixed the placement and angle of axis labels in 3D plots. - BVR 2010-11-07 New rc parameters examples.download and examples.directory allow bypassing the download mechanism in get_sample_data. - JKS 2010-08-21 Change Axis.set_view_interval() so that when updating an existing interval, it respects the orientation of that interval, and can enlarge but not reduce the interval. This fixes a bug in which Axis.set_ticks would change the view limits of an inverted axis. Whether set_ticks should be affecting the viewLim at all remains an open question. - EF 2010-08-16 Handle NaN's correctly in path analysis routines. Fixes a bug where the best location for a legend was not calculated correctly when the line contains NaNs. - MGD 2010-08-14 Fix bug in patch alpha handling, and in bar color kwarg - EF 2010-07-20 Return Qt4's default cursor when leaving the canvas - DSD 2010-07-06 Tagging for mpl 1.0 at r8502 2010-07-05 Added Ben Root's patch to put 3D plots in arbitrary axes, allowing you to mix 3d and 2d in different axes/subplots or to have multiple 3D plots in one figure. See examples/mplot3d/subplot3d_demo.py - JDH 2010-07-05 Preferred kwarg names in set_xlim are now 'left' and 'right'; in set_ylim, 'bottom' and 'top'; original kwargs are still accepted without complaint. - EF 2010-07-05 TkAgg and FltkAgg backends are now consistent with other interactive backends: when used in scripts from the command line (not from ipython -pylab), show blocks, and can be called more than once. - EF 2010-07-02 Modified CXX/WrapPython.h to fix "swab bug" on solaris so mpl can compile on Solaris with CXX6 in the trunk. Closes tracker bug 3022815 - JDH 2010-06-30 Added autoscale convenience method and corresponding pyplot function for simplified control of autoscaling; and changed axis, set_xlim, and set_ylim so that by default, they turn off the autoscaling on the relevent axis or axes. Therefore one can call set_xlim before plotting a line, for example, and the limits will be retained. - EF 2010-06-20 Added Axes.tick_params and corresponding pyplot function to control tick and tick label appearance after an Axes has been created. - EF 2010-06-09 Allow Axes.grid to control minor gridlines; allow Axes.grid and Axis.grid to control major and minor gridlines in the same method call. - EF 2010-06-06 Change the way we do split/dividend adjustments in finance.py to handle dividends and fix the zero division bug reported in sf bug 2949906 and 2123566. Note that volume is not adjusted because the Yahoo CSV does not distinguish between share split and dividend adjustments making it near impossible to get volume adjustement right (unless we want to guess based on the size of the adjustment or scrape the html tables, which we don't) - JDH 2010-06-06 Updated dateutil to 1.5 and pytz to 2010h. 2010-06-02 Add error_kw kwarg to Axes.bar(). - EF 2010-06-01 Fix pcolormesh() and QuadMesh to pass on kwargs as appropriate. - RM 2010-05-18 Merge mpl_toolkits.gridspec into the main tree. - JJL 2010-05-04 Improve backend_qt4 so it displays figures with the correct size - DSD 2010-04-20 Added generic support for connecting to a timer for events. This adds TimerBase, TimerGTK, TimerQT, TimerWx, and TimerTk to the backends and a new_timer() method to each backend's canvas to allow ease of creating a new timer. - RM 2010-04-20 Added margins() Axes method and pyplot function. - EF 2010-04-18 update the axes_grid documentation. -JJL 2010-04-18 Control MaxNLocator parameters after instantiation, and via Axes.locator_params method, with corresponding pyplot function. -EF 2010-04-18 Control ScalarFormatter offsets directly and via the Axes.ticklabel_format() method, and add that to pyplot. -EF 2010-04-16 Add a close_event to the backends. -RM 2010-04-06 modify axes_grid examples to use axes_grid1 and axisartist. -JJL 2010-04-06 rebase axes_grid using axes_grid1 and axisartist modules. -JJL 2010-04-06 axes_grid toolkit is splitted into two separate modules, axes_grid1 and axisartist. -JJL 2010-04-05 Speed up import: import pytz only if and when it is needed. It is not needed if the rc timezone is UTC. - EF 2010-04-03 Added color kwarg to Axes.hist(), based on work by Jeff Klukas. - EF 2010-03-24 refactor colorbar code so that no cla() is necessary when mappable is changed. -JJL 2010-03-22 fix incorrect rubber band during the zoom mode when mouse leaves the axes. -JJL 2010-03-21 x/y key during the zoom mode only changes the x/y limits. -JJL 2010-03-20 Added pyplot.sca() function suggested by JJL. - EF 2010-03-20 Added conditional support for new Tooltip API in gtk backend. - EF 2010-03-20 Changed plt.fig_subplot() to plt.subplots() after discussion on list, and changed its API to return axes as a numpy object array (with control of dimensions via squeeze keyword). FP. 2010-03-13 Manually brought in commits from branch ------------------------------------------------------------------------ r8191 | leejjoon | 2010-03-13 17:27:57 -0500 (Sat, 13 Mar 2010) | 1 line fix the bug that handles for scatter are incorrectly set when dpi!=72. Thanks to Ray Speth for the bug report. 2010-03-03 Manually brought in commits from branch via diff/patch (svnmerge is broken) ------------------------------------------------------------------------ r8175 | leejjoon | 2010-03-03 10:03:30 -0800 (Wed, 03 Mar 2010) | 1 line fix arguments of allow_rasterization.draw_wrapper ------------------------------------------------------------------------ r8174 | jdh2358 | 2010-03-03 09:15:58 -0800 (Wed, 03 Mar 2010) | 1 line added support for favicon in docs build ------------------------------------------------------------------------ r8173 | jdh2358 | 2010-03-03 08:56:16 -0800 (Wed, 03 Mar 2010) | 1 line applied Mattias get_bounds patch ------------------------------------------------------------------------ r8172 | jdh2358 | 2010-03-03 08:31:42 -0800 (Wed, 03 Mar 2010) | 1 line fix svnmerge download instructions ------------------------------------------------------------------------ r8171 | jdh2358 | 2010-03-03 07:47:48 -0800 (Wed, 03 Mar 2010) | 1 line 2010-02-25 add annotation_demo3.py that demonstrates new functionality. -JJL 2010-02-25 refactor Annotation to support arbitrary Transform as xycoords or textcoords. Also, if a tuple of two coordinates is provided, they are interpreted as coordinates for each x and y position. -JJL 2010-02-24 Added pyplot.fig_subplot(), to create a figure and a group of subplots in a single call. This offers an easier pattern than manually making figures and calling add_subplot() multiple times. FP 2010-02-17 Added Gokhan's and Mattias' customizable keybindings patch for the toolbar. You can now set the keymap.* properties in the matplotlibrc file. Newbindings were added for toggling log scaling on the x-axis. JDH 2010-02-16 Committed TJ's filled marker patch for left|right|bottom|top|full filled markers. See examples/pylab_examples/filledmarker_demo.py. JDH 2010-02-11 Added 'bootstrap' option to boxplot.

Patch by Neil Crighton. -ADS 2010-01-16 Applied patch by Ian Thomas to fix two contouring problems: now contourf handles interior masked regions, and the boundaries of line and filled contours coincide. - EF 2009-01-11 The color of legend patch follows the rc parameters axes.facecolor and axes.edgecolor. -JJL 2009-01-11 adjustable of Axes can be "box-forced" which allow sharing axes. -JJL 2009-01-11 Add add_click and pop_click methods in BlockingContourLabeler. -JJL 2010-01-03 Added rcParams['axes.color_cycle'] - EF 2010-01-03 Added Pierre's qt4 formlayout editor and toolbar button - JDH 2009-12-31 Add support for using math text as marker symbols (Thanks to tcb) - MGD 2009-12-31 Commit a workaround for a regression in PyQt4-4.6.{0,1} - DSD 2009-12-22 Fix cmap data for gist_earth_r, etc. -JJL 2009-12-20 spines: put spines in data coordinates, add set_bounds() call. -ADS 2009-12-18 Don't limit notch size in boxplot to q1-q3 range, as this is effectively making the data look better than it is. - ADS 2009-12-18 mlab.prctile handles even-length data, such that the median is the mean of the two middle values. - ADS 2009-12-15 Add raw-image (unsampled) support for the ps backend. - JJL 2009-12-14 Add patch_artist kwarg to boxplot, but keep old default. Convert boxplot_demo2.py to use the new patch_artist. - ADS 2009-12-06 axes_grid: reimplemented AxisArtist with FloatingAxes support. Added new examples. - JJL 2009-12-01 Applied Laurent Dufrechou's patch to improve blitting with the qt4 backend - DSD 2009-11-13 The pdf backend now allows changing the contents of a pdf file's information dictionary via PdfPages.infodict. - JKS 2009-11-12 font_manager.py should no longer cause EINTR on Python 2.6 (but will on the 2.5 version of subprocess). Also the fc-list command in that file was fixed so now it should actually find the list of fontconfig fonts. - JKS 2009-11-10 Single images, and all images in renderers with option_image_nocomposite (i.e. agg, macosx and the svg backend when rcParams['svg.image_noscale'] is True), are now drawn respecting the zorder relative to other artists. (Note that there may now be inconsistencies across backends when more than one image is drawn at varying zorders, but this change introduces correct behavior for the backends in which it's easy to do so.) 2009-10-21 Make AutoDateLocator more configurable by adding options to control the maximum and minimum number of ticks. Also add control of the intervals to be used for ticking. This does not change behavior but opens previously hard-coded behavior to runtime modification`. - RMM 2009-10-19 Add "path_effects" support for Text and Patch. See examples/pylab_examples/patheffect_demo.py -JJL 2009-10-19 Add "use_clabeltext" option to clabel. If True, clabels will be created with ClabelText class, which recalculates rotation angle of the label during the drawing time. -JJL 2009-10-16 Make AutoDateFormatter actually use any specified timezone setting.This was only working correctly when no timezone was specified. - RMM 2009-09-27 Beginnings of a capability to test the pdf backend. - JKS 2009-09-27 Add a savefig.extension rcparam to control the default filename extension used by savefig. - JKS =============================================== 2009-09-21 Tagged for release 0.99.1 2009-09-20 Fix usetex spacing errors in pdf backend. - JKS 2009-09-20 Add Sphinx extension to highlight IPython console sessions, originally authored (I think) by Michael Droetboom. - FP 2009-09-20 Fix off-by-one error in dviread.Tfm, and additionally protect against exceptions in case a dvi font is missing some metrics. - JKS 2009-09-15 Implement draw_text and draw_tex method of backend_base using the textpath module. Implement draw_tex method of the svg backend. - JJL 2009-09-15 Don't fail on AFM files containing floating-point bounding boxes - JKS 2009-09-13 AxesGrid : add modified version of colorbar.

See the example demo_annotation_box.py. -JJL 2009-08-07 BboxImage implemented. Two examples, demo_bboximage.py and demo_ribbon_box.py added. - JJL 2009-08-07 In an effort to simplify the backend API, all clipping rectangles and paths are now passed in using GraphicsContext objects, even on collections and images. Therefore: draw_path_collection(self, master_transform, cliprect, clippath, clippath_trans, paths, all_transforms, offsets, offsetTrans, facecolors, edgecolors, linewidths, linestyles, antialiaseds, urls) becomes: draw_path_collection(self, gc, master_transform, paths, all_transforms, offsets, offsetTrans, facecolors, edgecolors, linewidths, linestyles, antialiaseds, urls) draw_quad_mesh(self, master_transform, cliprect, clippath, clippath_trans, meshWidth, meshHeight, coordinates, offsets, offsetTrans, facecolors, antialiased, showedges) becomes: draw_quad_mesh(self, gc, master_transform, meshWidth, meshHeight, coordinates, offsets, offsetTrans, facecolors, antialiased, showedges) draw_image(self, x, y, im, bbox, clippath=None, clippath_trans=None) becomes: draw_image(self, gc, x, y, im) - MGD 2009-08-06 Tagging the 0.99.0 release at svn r7397 - JDH * fixed an alpha colormapping bug posted on sf 2832575 * fix typo in axes_divider.py. use nanmin, nanmax in angle_helper.py (patch by Christoph Gohlke) * remove dup gui event in enter/leave events in gtk * lots of fixes for os x binaries (Thanks Russell Owen) * attach gtk events to mpl events -- fixes sf bug 2816580 * applied sf patch 2815064 (middle button events for wx) and patch 2818092 (resize events for wx) * fixed boilerplate.py so it doesn't break the ReST docs. * removed a couple of cases of mlab.load * fixed rec2csv win32 file handle bug from sf patch 2831018 * added two examples from Josh Hemann: examples/pylab_examples/barchart_demo2.py and examples/pylab_examples/boxplot_demo2.py * handled sf bugs 2831556 and 2830525; better bar error messages and backend driver configs * added miktex win32 patch from sf patch 2820194 * apply sf patches 2830233 and 2823885 for osx setup and 64 bit; thanks Michiel 2009-08-04 Made cbook.get_sample_data make use of the ETag and Last-Modified headers of mod_dav_svn. - JKS 2009-08-03 Add PathCollection; modify contourf to use complex paths instead of simple paths with cuts. - EF 2009-08-03 Fixed boilerplate.py so it doesn't break the ReST docs. - JKS 2009-08-03 pylab no longer provides a load and save function.

Return the list of pprinted strings instead - JDH 2008-12-08 Some of the changes Michael made to improve the output of the property tables in the rest docs broke of made difficult to use some of the interactive doc helpers, eg setp and getp. Having all the rest markup in the ipython shell also confused the docstrings. I added a new rc param docstring.harcopy, to format the docstrings differently for hardcopy and other use. Ther ArtistInspector could use a little refactoring now since there is duplication of effort between the rest out put and the non-rest output - JDH 2008-12-08 Updated spectral methods (psd, csd, etc.) to scale one-sided densities by a factor of 2 and, optionally, scale all densities by the sampling frequency.

In fact, under the hood, these all call the same core to do computations. - RM 2008-11-11 Add 'pad_to' and 'sides' parameters to mlab.psd() to allow controlling of zero padding and returning of negative frequency components, respecitively. These are added in a way that does not change the API. - RM 2008-11-10 Fix handling of c kwarg by scatter; generalize is_string_like to accept numpy and numpy.ma string array scalars. - RM and EF 2008-11-09 Fix a possible EINTR problem in dviread, which might help when saving pdf files from the qt backend. - JKS 2008-11-05 Fix bug with zoom to rectangle and twin axes - MGD 2008-10-24 Added Jae Joon's fancy arrow, box and annotation enhancements -- see examples/pylab_examples/annotation_demo2.py 2008-10-23 Autoscaling is now supported with shared axes - EF 2008-10-23 Fixed exception in dviread that happened with Minion - JKS 2008-10-21 set_xlim, ylim now return a copy of the viewlim array to avoid modify inplace surprises 2008-10-20 Added image thumbnail generating function matplotlib.image.thumbnail.

(This was a regression since 0.90 caused by the refactoring of font_manager.py) - MGD 2007-12-05 Support arbitrary rotation of usetex text in Agg backend. - MGD 2007-12-04 Support '|' as a character in mathtext - MGD =============================================================== 2007-11-27 Released 0.91.1 at revision 4517 =============================================================== 2007-11-27 Released 0.91.0 at revision 4478 2007-11-13 All backends now support writing to a file-like object, not just a regular file. savefig() can be passed a file-like object in place of a file path. - MGD 2007-11-13 Improved the default backend selection at build time: SVG -> Agg -> TkAgg -> WXAgg -> GTK -> GTKAgg. The last usable backend in this progression will be chosen in the default config file. If a backend is defined in setup.cfg, that will be the default backend - DSD 2007-11-13 Improved creation of default config files at build time for traited config package - DSD 2007-11-12 Exposed all the build options in setup.cfg. These options are read into a dict called "options" by setupext.py. Also, added "-mpl" tags to the version strings for packages provided by matplotlib. Versions provided by mpl will be identified and updated on subsequent installs - DSD 2007-11-12 Added support for STIX fonts. A new rcParam, mathtext.fontset, can be used to choose between: 'cm': The TeX/LaTeX Computer Modern fonts 'stix': The STIX fonts (see stixfonts.org) 'stixsans': The STIX fonts, using sans-serif glyphs by default 'custom': A generic Unicode font, in which case the mathtext font must be specified using mathtext.bf, mathtext.it, mathtext.sf etc. Added a new example, stix_fonts_demo.py to show how to access different fonts and unusual symbols. - MGD 2007-11-12 Options to disable building backend extension modules moved from setup.py to setup.cfg - DSD 2007-11-09 Applied Martin Teichmann's patch 1828813: a QPainter is used in paintEvent, which has to be destroyed using the method end(). If matplotlib raises an exception before the call to end - and it does if you feed it with bad data - this method end() is never called and Qt4 will start spitting error messages 2007-11-09 Moved pyparsing back into matplotlib namespace. Don't use system pyparsing, API is too variable from one release to the next - DSD 2007-11-08 Made pylab use straight numpy instead of oldnumeric by default - EF 2007-11-08 Added additional record array utilites to mlab (rec2excel, rec2gtk, rec_join, rec_append_field, rec_drop_field) - JDH 2007-11-08 Updated pytz to version 2007g - DSD 2007-11-08 Updated pyparsing to version 1.4.8 - DSD 2007-11-08 Moved csv2rec to recutils and added other record array utilities - JDH 2007-11-08 If available, use existing pyparsing installation - DSD 2007-11-07 Removed old enthought.traits from lib/matplotlib, added Gael Varoquaux's enthought.traits-2.6b1, which is stripped of setuptools. The package is installed to site-packages if not already available - DSD 2007-11-05 Added easy access to minor tick properties; slight mod of patch by Pierre G-M - EF 2007-11-02 Commited Phil Thompson's patch 1599876, fixes to Qt4Agg backend and qt4 blitting demo - DSD 2007-11-02 Commited Phil Thompson's patch 1599876, fixes to Qt4Agg backend and qt4 blitting demo - DSD 2007-10-31 Made log color scale easier to use with contourf; automatic level generation now works. - EF 2007-10-29 TRANSFORMS REFACTORING The primary goal of this refactoring was to make it easier to extend matplotlib to support new kinds of projections. This is primarily an internal improvement, and the possible user-visible changes it allows are yet to come. The transformation framework was completely rewritten in Python (with Numpy). This will make it easier to add news kinds of transformations without writing C/C++ code. Transforms are composed into a 'transform tree', made of transforms whose value depends on other transforms (their children). When the contents of children change, their parents are automatically updated to reflect those changes. To do this an "invalidation" method is used: when children change, all of their ancestors are marked as "invalid". When the value of a transform is accessed at a later time, its value is recomputed only if it is invalid, otherwise a cached value may be used. This prevents unnecessary recomputations of transforms, and contributes to better interactive performance. The framework can be used for both affine and non-affine transformations. However, for speed, we want use the backend renderers to perform affine transformations whenever possible. Therefore, it is possible to perform just the affine or non-affine part of a transformation on a set of data. The affine is always assumed to occur after the non-affine. For any transform: full transform == non-affine + affine Much of the drawing has been refactored in terms of compound paths. Therefore, many methods have been removed from the backend interface and replaced with a a handful to draw compound paths. This will make updating the backends easier, since there is less to update. It also should make the backends more consistent in terms of functionality. User visible changes: - POLAR PLOTS: Polar plots are now interactively zoomable, and the r-axis labels can be interactively rotated. Straight line segments are now interpolated to follow the curve of the r-axis. - Non-rectangular clipping works in more backends and with more types of objects. - Sharing an axis across figures is now done in exactly the same way as sharing an axis between two axes in the same figure: fig1 = figure() fig2 = figure() ax1 = fig1.add_subplot(111) ax2 = fig2.add_subplot(111, sharex=ax1, sharey=ax1) - linestyles now include steps-pre, steps-post and steps-mid. The old step still works and is equivalent to step-pre. - Multiple line styles may be provided to a collection. See API_CHANGES for more low-level information about this refactoring. 2007-10-24 Added ax kwarg to Figure.colorbar and pyplot.colorbar - EF 2007-10-19 Removed a gsave/grestore pair surrounding _draw_ps, which was causing a loss graphics state info (see "EPS output problem - scatter & edgecolors" on mpl-dev, 2007-10-29) - DSD 2007-10-15 Fixed a bug in patches.Ellipse that was broken for aspect='auto'. Scale free ellipses now work properly for equal and auto on Agg and PS, and they fall back on a polygonal approximation for nonlinear transformations until we convince oursleves that the spline approximation holds for nonlinear transformations. Added unit/ellipse_compare.py to compare spline with vertex approx for both aspects. JDH 2007-10-05 remove generator expressions from texmanager and mpltraits. generator expressions are not supported by python-2.3 - DSD 2007-10-01 Made matplotlib.use() raise an exception if called after backends has been imported. - EF 2007-09-30 Modified update* methods of Bbox and Interval so they work with reversed axes. Prior to this, trying to set the ticks on a reversed axis failed with an uninformative error message. - EF 2007-09-30 Applied patches to axes3d to fix index error problem - EF 2007-09-24 Applied Eike Welk's patch reported on mpl-dev on 2007-09-22 Fixes a bug with multiple plot windows in the qt backend, ported the changes to backend_qt4 as well - DSD 2007-09-21 Changed cbook.reversed to yield the same result as the python reversed builtin - DSD 2007-09-13 The usetex support in the pdf backend is more usable now, so I am enabling it. - JKS 2007-09-12 Fixed a Axes.bar unit bug - JDH 2007-09-10 Made skiprows=1 the default on csv2rec - JDH 2007-09-09 Split out the plotting part of pylab and put it in pyplot.py; removed numerix from the remaining pylab.py, which imports everything from pyplot.py. The intention is that apart from cleanups, the result of importing from pylab is nearly unchanged, but there is the new alternative of importing from pyplot to get the state-engine graphics without all the numeric functions. Numpified examples; deleted two that were obsolete; modified some to use pyplot. - EF 2007-09-08 Eliminated gd and paint backends - EF 2007-09-06 .bmp file format is now longer an alias for .raw 2007-09-07 Added clip path support to pdf backend. - JKS 2007-09-06 Fixed a bug in the embedding of Type 1 fonts in PDF. Now it doesn't crash Preview.app. - JKS 2007-09-06 Refactored image saving code so that all GUI backends can save most image types. See FILETYPES for a matrix of backends and their supported file types. Backend canvases should no longer write their own print_figure() method -- instead they should write a print_xxx method for each filetype they can output and add an entry to their class-scoped filetypes dictionary. - MGD 2007-09-05 Fixed Qt version reporting in setupext.py - DSD 2007-09-04 Embedding Type 1 fonts in PDF, and thus usetex support via dviread, sort of works. To test, enable it by renaming _draw_tex to draw_tex. - JKS 2007-09-03 Added ability of errorbar show limits via caret or arrowhead ends on the bars; patch by Manual Metz. - EF 2007-09-03 Created type1font.py, added features to AFM and FT2Font (see API_CHANGES), started work on embedding Type 1 fonts in pdf files. - JKS 2007-09-02 Continued work on dviread.py. - JKS 2007-08-16 Added a set_extent method to AxesImage, allow data extent to be modified after initial call to imshow - DSD 2007-08-14 Fixed a bug in pyqt4 subplots-adjust. Thanks to Xavier Gnata for the report and suggested fix - DSD 2007-08-13 Use pickle to cache entire fontManager; change to using font_manager module-level function findfont wrapper for the fontManager.findfont method - EF 2007-08-11 Numpification and cleanup of mlab.py and some examples - EF 2007-08-06 Removed mathtext2 2007-07-31 Refactoring of distutils scripts. - Will not fail on the entire build if an optional Python package (e.g. Tkinter) is installed but its development headers are not (e.g. tk-devel). Instead, it will continue to build all other extensions. - Provide an overview at the top of the output to display what dependencies and their versions were found, and (by extension) what will be built. - Use pkg-config, when available, to find freetype2, since this was broken on Mac OS-X when using MacPorts in a non- standard location. 2007-07-30 Reorganized configuration code to work with traited config objects. The new config system is located in the matplotlib.config package, but it is disabled by default. To enable it, set NEWCONFIG=True in matplotlib.__init__.py. The new configuration system will still use the old matplotlibrc files by default. To switch to the experimental, traited configuration, set USE_TRAITED_CONFIG=True in config.__init__.py. 2007-07-29 Changed default pcolor shading to flat; added aliases to make collection kwargs agree with setter names, so updating works; related minor cleanups. Removed quiver_classic, scatter_classic, pcolor_classic. - EF 2007-07-26 Major rewrite of mathtext.py, using the TeX box layout model. There is one (known) backward incompatible change. The font commands (\cal, \rm, \it, \tt) now behave as TeX does: they are in effect until the next font change command or the end of the grouping. Therefore uses of $\cal{R}$ should be changed to ${\cal R}$. Alternatively, you may use the new LaTeX-style font commands (\mathcal, \mathrm, \mathit, \mathtt) which do affect the following group, eg. $\mathcal{R}$. Other new features include: - Math may be interspersed with non-math text. Any text with an even number of $'s (non-escaped) will be sent to the mathtext parser for layout. - Sub/superscripts are less likely to accidentally overlap. - Support for sub/superscripts in either order, eg. $x^i_j$ and $x_j^i$ are equivalent. - Double sub/superscripts (eg. $x_i_j$) are considered ambiguous and raise an exception. Use braces to disambiguate. - $\frac{x}{y}$ can be used for displaying fractions. - $\sqrt[3]{x}$ can be used to display the radical symbol with a root number and body. - $\left(\frac{x}{y}\right)$ may be used to create parentheses and other delimiters that automatically resize to the height of their contents. - Spacing around operators etc. is now generally more like TeX. - Added support (and fonts) for boldface (\bf) and sans-serif (\sf) symbols. - Log-like function name shortcuts are supported. For example, $\sin(x)$ may be used instead of ${\rm sin}(x)$ - Limited use of kerning for the easy case (same font) Behind the scenes, the pyparsing.py module used for doing the math parsing was updated to the latest stable version (1.4.6). A lot of duplicate code was refactored out of the Font classes. - MGD 2007-07-19 completed numpification of most trivial cases - NN 2007-07-19 converted non-numpy relicts throughout the code - NN 2007-07-19 replaced the Python code in numerix/ by a minimal wrapper around numpy that explicitly mentions all symbols that need to be addressed for further numpification - NN 2007-07-18 make usetex respect changes to rcParams. texmanager used to only configure itself when it was created, now it reconfigures when rcParams are changed.

Also made unit/memleak_gui.py more flexible with command-line options. - EF 2007-06-30 Split defaultParams into separate file rcdefaults (together with validation code). Some heavy refactoring was necessary to do so, but the overall behavior should be the same as before. - NN 2007-06-27 Added MPLCONFIGDIR for the default location for mpl data and configuration. useful for some apache installs where HOME is not writable. Tried to clean up the logic in _get_config_dir to support non-writable HOME where are writable HOME/.matplotlib already exists - JDH 2007-06-27 Fixed locale bug reported at http://sourceforge.net/tracker/index.php?func=detail&aid=1744154&group_id=80706&atid=560720 by adding a cbook.unicode_safe function - JDH 2007-06-27 Applied Micheal's tk savefig bugfix described at http://sourceforge.net/tracker/index.php?func=detail&aid=1716732&group_id=80706&atid=560720 Thanks Michael! 2007-06-27 Patch for get_py2exe_datafiles() to work with new directory layout.

Added label support to collections. - EF 2007-04-06 Removed deprecated support for a float value as a gray-scale; now it must be a string, like '0.5'. Added alpha kwarg to ColorConverter.to_rgba_list. - EF 2007-04-06 Fixed rotation of ellipses in pdf backend (sf bug #1690559) -JKS 2007-04-04 More matshow tweaks; documentation updates; new method set_bounds() for formatters and locators. - EF 2007-04-02 Fixed problem with imshow and matshow of integer arrays; fixed problems with changes to color autoscaling. - EF 2007-04-01 Made image color autoscaling work correctly with a tracking colorbar; norm.autoscale now scales unconditionally, while norm.autoscale_None changes only None-valued vmin, vmax. - EF 2007-03-31 Added a qt-based subplot-adjustment dialog - DSD 2007-03-30 Fixed a bug in backend_qt4, reported on mpl-dev - DSD 2007-03-26 Removed colorbar_classic from figure.py; fixed bug in Figure.clf() in which _axobservers was not getting cleared. Modernization and cleanups. - EF 2007-03-26 Refactored some of the units support -- units now live in the respective x and y Axis instances. See also API_CHANGES for some alterations to the conversion interface. JDH 2007-03-25 Fix masked array handling in quiver.py for numpy. (Numeric and numarray support for masked arrays is broken in other ways when using quiver. I didn't pursue that.) - ADS 2007-03-23 Made font_manager.py close opened files. - JKS 2007-03-22 Made imshow default extent match matshow - EF 2007-03-22 Some more niceties for xcorr -- a maxlags option, normed now works for xcorr as well as axorr, usevlines is supported, and a zero correlation hline is added. See examples/xcorr_demo.py. Thanks Sameer for the patch. - JDH 2007-03-21 Axes.vlines and Axes.hlines now create and returns a LineCollection, not a list of lines. This is much faster. The kwarg signature has changed, so consult the docs. Modified Axes.errorbar which uses vlines and hlines. See API_CHANGES; the return signature for these three functions is now different 2007-03-20 Refactored units support and added new examples - JDH 2007-03-19 Added Mike's units patch - JDH 2007-03-18 Matshow as an Axes method; test version matshow1() in pylab; added 'integer' Boolean kwarg to MaxNLocator initializer to force ticks at integer locations. - EF 2007-03-17 Preliminary support for clipping to paths agg - JDH 2007-03-17 Text.set_text() accepts anything convertible with '%s' - EF 2007-03-14 Add masked-array support to hist. - EF 2007-03-03 Change barh to take a kwargs dict and pass it to bar. Fixes sf bug #1669506. 2007-03-02 Add rc parameter pdf.inheritcolor, which disables all color-setting operations in the pdf backend. The idea is that you include the resulting file in another program and set the colors (both stroke and fill color) there, so you can use the same pdf file for e.g. a paper and a presentation and have them in the surrounding color. You will probably not want to draw figure and axis frames in that case, since they would be filled in the same color. - JKS 2007-02-26 Prevent building _wxagg.so with broken Mac OS X wxPython. - ADS 2007-02-23 Require setuptools for Python 2.3 - ADS 2007-02-22 WXAgg accelerator updates - KM WXAgg's C++ accelerator has been fixed to use the correct wxBitmap constructor. The backend has been updated to use new wxPython functionality to provide fast blit() animation without the C++ accelerator. This requires wxPython 2.8 or later. Previous versions of wxPython can use the C++ acclerator or the old pure Python routines. setup.py no longer builds the C++ accelerator when wxPython >= 2.8 is present. The blit() method is now faster regardless of which agg/wxPython conversion routines are used. 2007-02-21 Applied the PDF backend patch by Nicolas Grilly. This impacts several files and directories in matplotlib: - Created the directory lib/matplotlib/mpl-data/fonts/pdfcorefonts, holding AFM files for the 14 PDF core fonts. These fonts are embedded in every PDF viewing application. - setup.py: Added the directory pdfcorefonts to package_data. - lib/matplotlib/__init__.py: Added the default parameter 'pdf.use14corefonts'. When True, the PDF backend uses only the 14 PDF core fonts. - lib/matplotlib/afm.py: Added some keywords found in recent AFM files. Added a little workaround to handle Euro symbol. - lib/matplotlib/fontmanager.py: Added support for the 14 PDF core fonts. These fonts have a dedicated cache (file pdfcorefont.cache), not the same as for other AFM files (file .afmfont.cache). Also cleaned comments to conform to CODING_GUIDE. - lib/matplotlib/backends/backend_pdf.py: Added support for 14 PDF core fonts. Fixed some issues with incorrect character widths and encodings (works only for the most common encoding, WinAnsiEncoding, defined by the official PDF Reference). Removed parameter 'dpi' because it causes alignment issues. -JKS (patch by Nicolas Grilly) 2007-02-17 Changed ft2font.get_charmap, and updated all the files where get_charmap is mentioned - ES 2007-02-13 Added barcode demo- JDH 2007-02-13 Added binary colormap to cm - JDH 2007-02-13 Added twiny to pylab - JDH 2007-02-12 Moved data files into lib/matplotlib so that setuptools' develop mode works. Re-organized the mpl-data layout so that this source structure is maintained in the installation. (I.e. the 'fonts' and 'images' sub-directories are maintained in site-packages.) Suggest removing site-packages/matplotlib/mpl-data and ~/.matplotlib/ttffont.cache before installing - ADS 2007-02-07 Committed Rob Hetland's patch for qt4: remove references to text()/latin1(), plus some improvements to the toolbar layout - DSD =============================================================== 2007-02-06 Released 0.90.0 at revision 3003 2007-01-22 Extended the new picker API to text, patches and patch collections. Added support for user customizable pick hit testing and attribute tagging of the PickEvent - Details and examples in examples/pick_event_demo.py - JDH 2007-01-16 Begun work on a new pick API using the mpl event handling frameowrk. Artists will define their own pick method with a configurable epsilon tolerance and return pick attrs. All artists that meet the tolerance threshold will fire a PickEvent with artist dependent attrs; eg, a Line2D can set the indices attribute that shows the indices into the line that are within epsilon of the pick point. See examples/pick_event_demo.py. The implementation of pick for the remaining Artists remains to be done, but the core infrastructure at the level of event handling is in place with a proof-of-concept implementation for Line2D - JDH 2007-01-16 src/_image.cpp: update to use Py_ssize_t (for 64-bit systems). Use return value of fread() to prevent warning messages - SC. 2007-01-15 src/_image.cpp: combine buffer_argb32() and buffer_bgra32() into a new method color_conv(format) - SC 2007-01-14 backend_cairo.py: update draw_arc() so that examples/arctest.py looks correct - SC 2007-01-12 backend_cairo.py: enable clipping. Update draw_image() so that examples/contour_demo.py looks correct - SC 2007-01-12 backend_cairo.py: fix draw_image() so that examples/image_demo.py now looks correct - SC 2007-01-11 Added Axes.xcorr and Axes.acorr to plot the cross correlation of x vs y or the autocorrelation of x. pylab wrappers also provided. See examples/xcorr_demo.py - JDH 2007-01-10 Added "Subplot.label_outer" method. It will set the visibility of the ticklabels so that yticklabels are only visible in the first column and xticklabels are only visible in the last row - JDH 2007-01-02 Added additional kwarg documentation - JDH 2006-12-28 Improved error message for nonpositive input to log transform; added log kwarg to bar, barh, and hist, and modified bar method to behave sensibly by default when the ordinate has a log scale. (This only works if the log scale is set before or by the call to bar, hence the utility of the log kwarg.) - EF 2006-12-27 backend_cairo.py: update draw_image() and _draw_mathtext() to work with numpy - SC 2006-12-20 Fixed xpdf dependency check, which was failing on windows. Removed ps2eps dependency check. - DSD 2006-12-19 Added Tim Leslie's spectral patch - JDH 2006-12-17 Added rc param 'axes.formatter.limits' to control the default threshold for switching to scientific notation. Added convenience method Axes.ticklabel_format() for turning scientific notation on or off on either or both axes. - EF 2006-12-16 Added ability to turn control scientific notation in ScalarFormatter - EF 2006-12-16 Enhanced boxplot to handle more flexible inputs - EF 2006-12-13 Replaced calls to where() in colors.py with much faster clip() and putmask() calls; removed inappropriate uses of getmaskorNone (which should be needed only very rarely); all in response to profiling by David Cournapeau. Also fixed bugs in my 2-D array support from 12-09. - EF 2006-12-09 Replaced spy and spy2 with the new spy that combines marker and image capabilities - EF 2006-12-09 Added support for plotting 2-D arrays with plot: columns are plotted as in Matlab - EF 2006-12-09 Added linewidth kwarg to bar and barh; fixed arg checking bugs - EF 2006-12-07 Made pcolormesh argument handling match pcolor; fixed kwarg handling problem noted by Pierre GM - EF 2006-12-06 Made pcolor support vector X and/or Y instead of requiring 2-D arrays - EF 2006-12-05 Made the default Artist._transform None (rather than invoking identity_transform for each artist only to have it overridden later). Use artist.get_transform() rather than artist._transform, even in derived classes, so that the default transform will be created lazily as needed - JDH 2006-12-03 Added LogNorm to colors.py as illustrated by examples/pcolor_log.py, based on suggestion by Jim McDonald. Colorbar modified to handle LogNorm. Norms have additional "inverse" method. - EF 2006-12-02 Changed class names in colors.py to match convention: normalize -> Normalize, no_norm -> NoNorm. Old names are still available. Changed __init__.py rc defaults to match those in matplotlibrc - EF 2006-11-22 Fixed bug in set_*lim that I had introduced on 11-15 - EF 2006-11-22 Added examples/clippedline.py, which shows how to clip line data based on view limits -- it also changes the marker style when zoomed in - JDH 2006-11-21 Some spy bug-fixes and added precision arg per Robert C's suggestion - JDH 2006-11-19 Added semi-automatic docstring generation detailing all the kwargs that functions take using the artist introspection tools; eg 'help text now details the scatter kwargs that control the Text properties - JDH 2006-11-17 Removed obsolete scatter_classic, leaving a stub to raise NotImplementedError; same for pcolor_classic - EF 2006-11-15 Removed obsolete pcolor_classic - EF 2006-11-15 Fixed 1588908 reported by Russel Owen; factored nonsingular method out of ticker.py, put it into transforms.py as a function, and used it in set_xlim and set_ylim. - EF 2006-11-14 Applied patch 1591716 by Ulf Larssen to fix a bug in apply_aspect. Modified and applied patch 1594894 by mdehoon to fix bugs and improve formatting in lines.py. Applied patch 1573008 by Greg Willden to make psd etc. plot full frequency range for complex inputs. - EF 2006-11-14 Improved the ability of the colorbar to track changes in corresponding image, pcolor, or contourf. - EF 2006-11-11 Fixed bug that broke Numeric compatibility; added support for alpha to colorbar. The alpha information is taken from the mappable object, not specified as a kwarg. - EF 2006-11-05 Added broken_barh function for makring a sequence of horizontal bars broken by gaps -- see examples/broken_barh.py 2006-11-05 Removed lineprops and markerprops from the Annotation code and replaced them with an arrow configurable with kwarg arrowprops. See examples/annotation_demo.py - JDH 2006-11-02 Fixed a pylab subplot bug that was causing axes to be deleted with hspace or wspace equals zero in subplots_adjust - JDH 2006-10-31 Applied axes3d patch 1587359 http://sourceforge.net/tracker/index.php?func=detail&aid=1587359&group_id=80706&atid=560722 JDH =============================================================== 2006-10-26 Released 0.87.7 at revision 2835 2006-10-25 Made "tiny" kwarg in Locator.nonsingular much smaller - EF 2006-10-17 Closed sf bug 1562496 update line props dash/solid/cap/join styles - JDH 2006-10-17 Complete overhaul of the annotations API and example code - See matplotlib.text.Annotation and examples/annotation_demo.py JDH 2006-10-12 Committed Manuel Metz's StarPolygon code and examples/scatter_star_poly.py - JDH 2006-10-11 commented out all default values in matplotlibrc.template Default values should generally be taken from defaultParam in __init__.py - the file matplotlib should only contain those values that the user wants to explicitly change from the default. (see thread "marker color handling" on matplotlib-devel) 2006-10-10 Changed default comment character for load to '#' - JDH 2006-10-10 deactivated rcfile-configurability of markerfacecolor and markeredgecolor. Both are now hardcoded to the special value 'auto' to follow the line color. Configurability at run-time (using function arguments) remains functional. - NN 2006-10-07 introduced dummy argument magnification=1.0 to FigImage.make_image to satisfy unit test figimage_demo.py The argument is not yet handled correctly, which should only show up when using non-standard DPI settings in PS backend, introduced by patch #1562394. - NN 2006-10-06 add backend-agnostic example: simple3d.py - NN 2006-09-29 fix line-breaking for SVG-inline images (purely cosmetic) - NN 2006-09-29 reworked set_linestyle and set_marker markeredgecolor and markerfacecolor now default to a special value "auto" that keeps the color in sync with the line color further, the intelligence of axes.plot is cleaned up, improved and simplified. Complete compatibility cannot be guaranteed, but the new behavior should be much more predictable (see patch #1104615 for details) - NN 2006-09-29 changed implementation of clip-path in SVG to work around a limitation in inkscape - NN 2006-09-29 added two options to matplotlibrc: svg.image_inline svg.image_noscale see patch #1533010 for details - NN 2006-09-29 axes.py: cleaned up kwargs checking - NN 2006-09-29 setup.py: cleaned up setup logic - NN 2006-09-29 setup.py: check for required pygtk versions, fixes bug #1460783 - SC =============================================================== 2006-09-27 Released 0.87.6 at revision 2783 2006-09-24 Added line pointers to the Annotation code, and a pylab interface. See matplotlib.text.Annotation, examples/annotation_demo.py and examples/annotation_demo_pylab.py - JDH 2006-09-18 mathtext2.py: The SVG backend now supports the same things that the AGG backend does. Fixed some bugs with rendering, and out of bounds errors in the AGG backend - ES. Changed the return values of math_parse_s_ft2font_svg to support lines (fractions etc.) 2006-09-17 Added an Annotation class to facilitate annotating objects and an examples file examples/annotation_demo.py. I want to add dash support as in TextWithDash, but haven't decided yet whether inheriting from TextWithDash is the right base class or if another approach is needed - JDH =============================================================== 2006-09-05 Released 0.87.5 at revision 2761 2006-09-04 Added nxutils for some numeric add-on extension code -- specifically a better/more efficient inside polygon tester (see unit/inside_poly_*.py) - JDH 2006-09-04 Made bitstream fonts the rc default - JDH 2006-08-31 Fixed alpha-handling bug in ColorConverter, affecting collections in general and contour/contourf in particular. - EF 2006-08-30 ft2font.cpp: Added draw_rect_filled method (now used by mathtext2 to draw the fraction bar) to FT2Font - ES 2006-08-29 setupext.py: wrap calls to tk.getvar() with str(). On some systems, getvar returns a Tcl_Obj instead of a string - DSD 2006-08-28 mathtext2.py: Sub/superscripts can now be complex (i.e. fractions etc.). The demo is also updated - ES 2006-08-28 font_manager.py: Added /usr/local/share/fonts to list of X11 font directories - DSD 2006-08-28 mahtext2.py: Initial support for complex fractions. Also, rendering is now completely separated from parsing. The sub/superscripts now work better. Updated the mathtext2_demo.py - ES 2006-08-27 qt backends: don't create a QApplication when backend is imported, do it when the FigureCanvasQt is created. Simplifies applications where mpl is embedded in qt. Updated embedding_in_qt* examples - DSD 2006-08-27 mahtext2.py: Now the fonts are searched in the OS font dir and in the mpl-data dir. Also env is not a dict anymore. - ES 2006-08-26 minor changes to __init__.py, mathtex2_demo.py. Added matplotlibrc key "mathtext.mathtext2" (removed the key "mathtext2") - ES 2006-08-21 mathtext2.py: Initial support for fractions Updated the mathtext2_demo.py _mathtext_data.py: removed "\" from the unicode dicts mathtext.py: Minor modification (because of _mathtext_data.py)- ES 2006-08-20 Added mathtext2.py: Replacement for mathtext.py. Supports _ ^, \rm, \cal etc., \sin, \cos etc., unicode, recursive nestings, inline math mode. The only backend currently supported is Agg __init__.py: added new rc params for mathtext2 added mathtext2_demo.py example - ES 2006-08-19 Added embedding_in_qt4.py example - DSD 2006-08-11 Added scale free Ellipse patch for Agg - CM 2006-08-10 Added converters to and from julian dates to matplotlib.dates (num2julian and julian2num) - JDH 2006-08-08 Fixed widget locking so multiple widgets could share the event handling - JDH 2006-08-07 Added scale free Ellipse patch to SVG and PS - CM 2006-08-05 Re-organized imports in numerix for numpy 1.0b2 -- TEO 2006-08-04 Added draw_markers to PDF backend. - JKS 2006-08-01 Fixed a bug in postscript's rendering of dashed lines - DSD 2006-08-01 figure.py: savefig() update docstring to add support for 'format' argument. backend_cairo.py: print_figure() add support 'format' argument. - SC 2006-07-31 Don't let postscript's xpdf distiller compress images - DSD 2006-07-31 Added shallowcopy() methods to all Transformations; removed copy_bbox_transform and copy_bbox_transform_shallow from transforms.py; added offset_copy() function to transforms.py to facilitate positioning artists with offsets. See examples/transoffset.py. - EF 2006-07-31 Don't let postscript's xpdf distiller compress images - DSD 2006-07-29 Fixed numerix polygon bug reported by Nick Fotopoulos. Added inverse_numerix_xy() transform method. Made autoscale_view() preserve axis direction (e.g., increasing down).- EF 2006-07-28 Added shallow bbox copy routine for transforms -- mainly useful for copying transforms to apply offset to. - JDH 2006-07-28 Added resize method to FigureManager class for Qt and Gtk backend - CM 2006-07-28 Added subplots_adjust button to Qt backend - CM 2006-07-26 Use numerix more in collections. Quiver now handles masked arrays. - EF 2006-07-22 Fixed bug #1209354 - DSD 2006-07-22 make scatter() work with the kwarg "color". Closes bug 1285750 - DSD 2006-07-20 backend_cairo.py: require pycairo 1.2.0. print_figure() update to output SVG using cairo. 2006-07-19 Added blitting for Qt4Agg - CM 2006-07-19 Added lasso widget and example examples/lasso_demo.py - JDH 2006-07-18 Added blitting for QtAgg backend - CM 2006-07-17 Fixed bug #1523585: skip nans in semilog plots - DSD 2006-07-12 Add support to render the scientific notation label over the right-side y-axis - DSD =============================================================== 2006-07-11 Released 0.87.4 at revision 2558 2006-07-07 Fixed a usetex bug with older versions of latex - DSD 2006-07-07 Add compatibility for NumPy 1.0 - TEO 2006-06-29 Added a Qt4Agg backend. Thank you James Amundson - DSD 2006-06-26 Fixed a usetex bug. On windows, usetex will prcess postscript output in the current directory rather than in a temp directory. This is due to the use of spaces and tildes in windows paths, which cause problems with latex. The subprocess module is no longer used. - DSD 2006-06-22 Various changes to bar(), barh(), and hist(). Added 'edgecolor' keyword arg to bar() and barh(). The x and y args in barh() have been renamed to width and bottom respectively, and their order has been swapped to maintain a (position, value) order ala matlab. left, height, width and bottom args can now all be scalars or sequences. barh() now defaults to edge alignment instead of center alignment. Added a keyword arg 'align' to bar(), barh() and hist() that controls between edge or center bar alignment. Fixed ignoring the rcParams['patch.facecolor'] for bar color in bar() and barh(). Fixed ignoring the rcParams['lines.color'] for error bar color in bar() and barh(). Fixed a bug where patches would be cleared when error bars were plotted if rcParams['axes.hold'] was False. - MAS 2006-06-22 Added support for numerix 2-D arrays as alternatives to a sequence of (x,y) tuples for specifying paths in collections, quiver, contour, pcolor, transforms. Fixed contour bug involving setting limits for color mapping. Added numpy-style all() to numerix. - EF 2006-06-20 Added custom FigureClass hook to pylab interface - see examples/custom_figure_class.py 2006-06-16 Added colormaps from gist (gist_earth, gist_stern, gist_rainbow, gist_gray, gist_yarg, gist_heat, gist_ncar) - JW 2006-06-16 Added a pointer to parent in figure canvas so you can access the container with fig.canvas.manager. Useful if you want to set the window title, eg in gtk fig.canvas.manager.window.set_title, though a GUI neutral method would be preferable JDH 2006-06-16 Fixed colorbar.py to handle indexed colors (i.e., norm = no_norm()) by centering each colored region on its index. - EF 2006-06-15 Added scalex and scaley to Axes.autoscale_view to support selective autoscaling just the x or y axis, and supported these command in plot so you can say plot(something, scaley=False) and just the x axis will be autoscaled. Modified axvline and axhline to support this, so for example axvline will no longer autoscale the y axis. JDH 2006-06-13 Fix so numpy updates are backward compatible - TEO 2006-06-12 Updated numerix to handle numpy restructuring of oldnumeric - TEO 2006-06-12 Updated numerix.fft to handle numpy restructuring Added ImportError to numerix.linear_algebra for numpy -TEO 2006-06-11 Added quiverkey command to pylab and Axes, using QuiverKey class in quiver.py. Changed pylab and Axes to use quiver2 if possible, but drop back to the newly-renamed quiver_classic if necessary. Modified examples/quiver_demo.py to illustrate the new quiver and quiverkey. Changed LineCollection implementation slightly to improve compatibility with PolyCollection. - EF 2006-06-11 Fixed a usetex bug for windows, running latex on files with spaces in their names or paths was failing - DSD 2006-06-09 Made additions to numerix, changes to quiver to make it work with all numeric flavors. - EF 2006-06-09 Added quiver2 function to pylab and method to axes, with implementation via a Quiver class in quiver.py. quiver2 will replace quiver before the next release; it is placed alongside it initially to facilitate testing and transition. See also examples/quiver2_demo.py. - EF 2006-06-08 Minor bug fix to make ticker.py draw proper minus signs with usetex - DSD =============================================================== 2006-06-06 Released 0.87.3 at revision 2432 2006-05-30 More partial support for polygons with outline or fill, but not both. Made LineCollection inherit from ScalarMappable. - EF 2006-05-29 Yet another revision of aspect-ratio handling. - EF 2006-05-27 Committed a patch to prevent stroking zero-width lines in the svg backend - DSD 2006-05-24 Fixed colorbar positioning bug identified by Helge Avlesen, and improved the algorithm; added a 'pad' kwarg to control the spacing between colorbar and parent axes. - EF 2006-05-23 Changed color handling so that collection initializers can take any mpl color arg or sequence of args; deprecated float as grayscale, replaced by string representation of float. - EF 2006-05-19 Fixed bug: plot failed if all points were masked - EF 2006-05-19 Added custom symbol option to scatter - JDH 2006-05-18 New example, multi_image.py; colorbar fixed to show offset text when the ScalarFormatter is used; FixedFormatter augmented to accept and display offset text. - EF 2006-05-14 New colorbar; old one is renamed to colorbar_classic. New colorbar code is in colorbar.py, with wrappers in figure.py and pylab.py. Fixed aspect-handling bug reported by Michael Mossey. Made backend_bases.draw_quad_mesh() run.- EF 2006-05-08 Changed handling of end ranges in contourf: replaced "clip-ends" kwarg with "extend". See docstring for details. -EF 2006-05-08 Added axisbelow to rc - JDH 2006-05-08 If using PyGTK require version 2.2+ - SC 2006-04-19 Added compression support to PDF backend, controlled by new pdf.compression rc setting. - JKS 2006-04-19 Added Jouni's PDF backend 2006-04-18 Fixed a bug that caused agg to not render long lines 2006-04-16 Masked array support for pcolormesh; made pcolormesh support the same combinations of X,Y,C dimensions as pcolor does; improved (I hope) description of grid used in pcolor, pcolormesh. - EF 2006-04-14 Reorganized axes.py - EF 2006-04-13 Fixed a bug Ryan found using usetex with sans-serif fonts and exponential tick labels - DSD 2006-04-11 Refactored backend_ps and backend_agg to prevent module-level texmanager imports. Now these imports only occur if text.usetex rc setting is true - DSD 2006-04-10 Committed changes required for building mpl on win32 platforms with visual studio. This allows wxpython blitting for fast animations. - CM 2006-04-10 Fixed an off-by-one bug in Axes.change_geometry. 2006-04-10 Fixed bug in pie charts where wedge wouldn't have label in legend. Submitted by Simon Hildebrandt. - ADS 2006-05-06 Usetex makes temporary latex and dvi files in a temporary directory, rather than in the user's current working directory - DSD 2006-04-05 Apllied Ken's wx deprecation warning patch closing sf patch #1465371 - JDH 2006-04-05 Added support for the new API in the postscript backend. Allows values to be masked using nan's, and faster file creation - DSD 2006-04-05 Use python's subprocess module for usetex calls to external programs. subprocess catches when they exit abnormally so an error can be raised. - DSD 2006-04-03 Fixed the bug in which widgets would not respond to events. This regressed the twinx functionality, so I also updated subplots_adjust to update axes that share an x or y with a subplot instance. - CM 2006-04-02 Moved PBox class to transforms and deleted pbox.py; made pylab axis command a thin wrapper for Axes.axis; more tweaks to aspect-ratio handling; fixed Axes.specgram to account for the new imshow default of unit aspect ratio; made contour set the Axes.dataLim. - EF 2006-03-31 Fixed the Qt "Underlying C/C++ object deleted" bug. - JRE 2006-03-31 Applied Vasily Sulatskov's Qt Navigation Toolbar enhancement. - JRE 2006-03-31 Ported Norbert's rewriting of Halldor's stineman_interp algorithm to make it numerix compatible and added code to matplotlib.mlab. See examples/interp_demo.py - JDH 2006-03-30 Fixed a bug in aspect ratio handling; blocked potential crashes when panning with button 3; added axis('image') support. - EF 2006-03-28 More changes to aspect ratio handling; new PBox class in new file pbox.py to facilitate resizing and repositioning axes; made PolarAxes maintain unit aspect ratio. - EF 2006-03-23 Refactored TextWithDash class to inherit from, rather than delegate to, the Text class. Improves object inspection and closes bug # 1357969 - DSD 2006-03-22 Improved aspect ratio handling, including pylab interface. Interactive resizing, pan, zoom of images and plots (including panels with a shared axis) should work. Additions and possible refactoring are still likely. - EF 2006-03-21 Added another colorbrewer colormap (RdYlBu) - JSWHIT 2006-03-21 Fixed tickmarks for logscale plots over very large ranges.

The main change is that Locator.nonsingular now adjusts vmin and vmax if they are nearly the same, not just if they are equal. A new kwarg, "tiny", sets the threshold. - EF 2006-03-14 Added import of compatibility library for newer numpy linear_algebra - TEO 2006-03-12 Extended "load" function to support individual columns and moved "load" and "save" into matplotlib.mlab so they can be used outside of pylab -- see examples/load_converter.py - JDH 2006-03-12 Added AutoDateFormatter and AutoDateLocator submitted by James Evans. Try the load_converter.py example for a demo. - ADS 2006-03-11 Added subprocess module from python-2.4 - DSD 2006-03-11 Fixed landscape orientation support with the usetex option.

You should define font.size in pts, which will set the "medium" or default fontsize. Special text sizes like axis labels or tick labels can be given relative font sizes like small, large, x-large, etc. and will scale accordingly. - DSD 2006-02-08 Added py2exe specific datapath check again. Also added new py2exe helper function get_py2exe_datafiles for use in py2exe setup.py scripts. - CM 2006-02-02 Added box function to pylab 2006-02-02 Fixed a problem in setupext.py, tk library formatted in unicode caused build problems - DSD 2006-02-01 Dropped TeX engine support in usetex to focus on LaTeX. - DSD 2006-01-29 Improved usetex option to respect the serif, sans-serif, monospace, and cursive rc settings.

Overrides the install_data command. - CM 2006-01-24 Don't use character typecodes in cntr.c --- changed to use defined typenumbers instead. - TEO 2006-01-24 Fixed some bugs in usetex's and ps.usedistiller's dependency 2006-01-24 Added masked array support to scatter - EF 2006-01-24 Fixed some bugs in usetex's and ps.usedistiller's dependency checking - DSD =============================================================== 2006-01-24 Released 0.86.2 2006-01-20 Added a converters dict to pylab load to convert selected coloumns to float -- especially useful for files with date strings, uses a datestr2num converter - JDH 2006-01-20 Added datestr2num to matplotlib dates to convert a string or sequence of strings to a matplotlib datenum 2006-01-18 Added quadrilateral pcolormesh patch 1409190 by Alex Mont and Paul Kienzle -- this is *Agg only for now. See examples/quadmesh_demo.py - JDH 2006-01-18 Added Jouni's boxplot patch - JDH 2006-01-18 Added comma delimiter for pylab save - JDH 2006-01-12 Added Ryan's legend patch - JDH 2006-1-12 Fixed numpy / numeric to use .dtype.char to keep in SYNC with numpy SVN =============================================================== 2006-1-11 Released 0.86.1 2006-1-11 Fixed setup.py for win32 build and added rc template to the MANIFEST.in 2006-1-10 Added xpdf distiller option. matplotlibrc ps.usedistiller can now be none, false, ghostscript, or xpdf. Validation checks for dependencies. This needs testing, but the xpdf option should produce the highest-quality output and small file sizes - DSD 2006-01-10 For the usetex option, backend_ps now does all the LaTeX work in the os's temp directory - DSD 2006-1-10 Added checks for usetex dependencies. - DSD ======================================================================= 2006-1-9 Released 0.86 2006-1-4 Changed to support numpy (new name for scipy_core) - TEO 2006-1-4 Added Mark's scaled axes patch for shared axis 2005-12-28 Added Chris Barker's build_wxagg patch - JDH 2005-12-27 Altered numerix/scipy to support new scipy package structure - TEO 2005-12-20 Fixed Jame's Boyles date tick reversal problem - JDH 2005-12-20 Added Jouni's rc patch to support lists of keys to set on - JDH 2005-12-12 Updated pyparsing and mathtext for some speed enhancements (Thanks Paul McGuire) and minor fixes to scipy numerix and setuptools 2005-12-12 Matplotlib data is now installed as package_data in the matplotlib module. This gets rid of checking the many possibilities in matplotlib._get_data_path() - CM 2005-12-11 Support for setuptools/pkg_resources to build and use matplotlib as an egg. Still allows matplotlib to exist using a traditional distutils install. - ADS 2005-12-03 Modified setup to build matplotlibrc based on compile time findings. It will set numerix in the order of scipy, numarray, Numeric depending on which are founds, and backend as in preference order GTKAgg, WXAgg, TkAgg, GTK, Agg, PS 2005-12-03 Modified scipy patch to support Numeric, scipy and numarray Some work remains to be done because some of the scipy imports are broken if only the core is installed. Eg apparently we need from scipy.basic.fftpack import * rather than from scipy.fftpack import * 2005-12-03 Applied some fixes to Nicholas Young's nonuniform image patch 2005-12-01 Applied Alex Gontmakher hatch patch - PS only for now 2005-11-30 Added Rob McMullen's EMF patch 2005-11-30 Added Daishi's patch for scipy 2005-11-30 Fixed out of bounds draw markers segfault in agg 2005-11-28 Got TkAgg blitting working 100% (cross fingers) correctly. - CM 2005-11-27 Multiple changes in cm.py, colors.py, figure.py, image.py, contour.py, contour_demo.py; new _cm.py, examples/image_masked.py. 1) Separated the color table data from cm.py out into a new file, _cm.py, to make it easier to find the actual code in cm.py and to add new colormaps. Also added some line breaks to the color data dictionaries. Everything from _cm.py is imported by cm.py, so the split should be transparent. 2) Enabled automatic generation of a colormap from a list of colors in contour; see modified examples/contour_demo.py. 3) Support for imshow of a masked array, with the ability to specify colors (or no color at all) for masked regions, and for regions that are above or below the normally mapped region. See examples/image_masked.py. 4) In support of the above, added two new classes, ListedColormap, and no_norm, to colors.py, and modified the Colormap class to include common functionality. Added a clip kwarg to the normalize class. Reworked color handling in contour.py, especially in the ContourLabeller mixin. - EF 2005-11-25 Changed text.py to ensure color is hashable. EF ======================================================================= 2005-11-16 Released 0.85 2005-11-16 Changed the default default linewidth in rc to 1.0 2005-11-16 Replaced agg_to_gtk_drawable with pure pygtk pixbuf code in backend_gtkagg.

The new SpanSelector supports horizontal and vertical span selection, and the appropriate min/max is returned. - CM 2005-11-08 Added lineprops dialog for gtk 2005-11-03 Added FIFOBuffer class to mlab to support real time feeds and examples/fifo_buffer.py 2005-11-01 Contributed Nickolas Young's patch for afm mathtext to support mathtext based upon the standard postscript Symbol font when ps.usetex = True. 2005-10-26 Added support for scatter legends - thanks John Gill 2005-10-20 Fixed image clipping bug that made some tex labels disappear. JDH 2005-10-14 Removed sqrt from dvipng 1.6 alpha channel mask. 2005-10-14 Added width kwarg to hist function 2005-10-10 Replaced all instances of os.rename with shutil.move 2005-10-05 Added Michael Brady's ydate patch 2005-10-04 Added rkern's texmanager patch 2005-09-25 contour.py modified to use a single ContourSet class that handles filled contours, line contours, and labels; added keyword arg (clip_ends) to contourf. Colorbar modified to work with new ContourSet object; if the ContourSet has lines rather than polygons, the colorbar will follow suit. Fixed a bug introduced in 0.84, in which contourf(...,colors=...) was broken - EF ======================================================================= 2005-09-19 Released 0.84 2005-09-14 Added a new 'resize_event' which triggers a callback with a backend_bases.ResizeEvent object - JDH 2005-09-14 font_manager.py: removed chkfontpath from x11FontDirectory() - SC 2005-09-14 Factored out auto date locator/formatter factory code into matplotlib.date.date_ticker_factory; applies John Bryne's quiver patch. 2005-09-13 Added Mark's axes positions history patch #1286915 2005-09-09 Added support for auto canvas resizing with fig.set_figsize_inches(9,5,forward=True) # inches OR fig.resize(400,300) # pixels 2005-09-07 figure.py: update Figure.draw() to use the updated renderer.draw_image() so that examples/figimage_demo.py works again. examples/stock_demo.py: remove data_clipping (which no longer exists) - SC 2005-09-06 Added Eric's tick.direction patch: in or out in rc 2005-09-06 Added Martin's rectangle selector widget 2005-09-04 Fixed a logic err in text.py that was preventing rgxsuper from matching - JDH 2005-08-29 Committed Ken's wx blit patch #1275002 2005-08-26 colorbar modifications - now uses contourf instead of imshow so that colors used by contourf are displayed correctly. Added two new keyword args (cspacing and clabels) that are only relevant for ContourMappable images - JSWHIT 2005-08-24 Fixed a PS image bug reported by Darren - JDH 2005-08-23 colors.py: change hex2color() to accept unicode strings as well as normal strings. Use isinstance() instead of types.IntType etc - SC 2005-08-16 removed data_clipping line and rc property - JDH 2005-08-22 backend_svg.py: Remove redundant "x=0.0 y=0.0" from svg element.

See examples/widgets/cursor.py and examples/widgets/span_selector.py - JDH 2005-07-26 added draw event to mpl event hierarchy -- triggered on figure.draw 2005-07-26 backend_gtk.py: allow 'f' key to toggle window fullscreen mode 2005-07-26 backend_svg.py: write "<.../>" elements all on one line and remove surplus spaces - SC 2005-07-25 backend_svg.py: simplify code by deleting GraphicsContextSVG and RendererSVG.new_gc(), and moving the gc.get_capstyle() code into RendererSVG._get_gc_props_svg() - SC 2005-07-24 backend_gtk.py: call FigureCanvasBase.motion_notify_event() on all motion-notify-events, not just ones where a modifier key or button has been pressed (fixes bug report from Niklas Volbers) - SC 2005-07-24 backend_gtk.py: modify print_figure() use own pixmap, fixing problems where print_figure() overwrites the display pixmap. return False from all button/key etc events - to allow the event to propagate further - SC 2005-07-23 backend_gtk.py: change expose_event from using set_back_pixmap(); clear() to draw_drawable() - SC 2005-07-23 backend_gtk.py: removed pygtk.require() matplotlib/__init__.py: delete 'FROZEN' and 'McPLError' which are no longer used - SC 2005-07-22 backend_gdk.py: removed pygtk.require() - SC 2005-07-21 backend_svg.py: Remove unused imports. Remove methods doc strings which just duplicate the docs from backend_bases.py. Rename draw_mathtext to _draw_mathtext. - SC 2005-07-17 examples/embedding_in_gtk3.py: new example demonstrating placing a FigureCanvas in a gtk.ScrolledWindow - SC 2005-07-14 Fixed a Windows related bug (#1238412) in texmanager - DSD 2005-07-11 Fixed color kwarg bug, setting color=1 or 0 caused an exception - DSD 2005-07-07 Added Eric's MA set_xdata Line2D fix - JDH 2005-07-06 Made HOME/.matplotlib the new config dir where the matplotlibrc file, the ttf.cache, and the tex.cache live. The new default filenames in .matplotlib have no leading dot and are not hidden. Eg, the new names are matplotlibrc tex.cache ttffont.cache. This is how ipython does it so it must be right. If old files are found, a warning is issued and they are moved to the new location. Also fixed texmanager to put all files, including temp files in ~/.matplotlib/tex.cache, which allows you to usetex in non-writable dirs. 2005-07-05 Fixed bug #1231611 in subplots adjust layout. The problem was that the text cacheing mechanism was not using the transformation affine in the key. - JDH 2005-07-05 Fixed default backend import problem when using API (SF bug # 1209354 - see API_CHANGES for more info - JDH 2005-07-04 backend_gtk.py: require PyGTK version 2.0.0 or higher - SC 2005-06-30 setupext.py: added numarray_inc_dirs for building against numarray when not installed in standard location - ADS 2005-06-27 backend_svg.py: write figure width, height as int, not float. Update to fix some of the pychecker warnings - SC 2005-06-23 Updated examples/agg_test.py to demonstrate curved paths and fills - JDH 2005-06-21 Moved some texmanager and backend_agg tex caching to class level rather than instance level - JDH 2005-06-20 setupext.py: fix problem where _nc_backend_gdk is installed to the wrong directory - SC 2005-06-19 Added 10.4 support for CocoaAgg. - CM 2005-06-18 Move Figure.get_width_height() to FigureCanvasBase and return int instead of float. - SC 2005-06-18 Applied Ted Drain's QtAgg patch: 1) Changed the toolbar to be a horizontal bar of push buttons instead of a QToolbar and updated the layout algorithms in the main window accordingly. This eliminates the ability to drag and drop the toolbar and detach it from the window. 2) Updated the resize algorithm in the main window to show the correct size for the plot widget as requested. This works almost correctly right now. It looks to me like the final size of the widget is off by the border of the main window but I haven't figured out a way to get that information yet. We could just add a small margin to the new size but that seems a little hacky. 3) Changed the x/y location label to be in the toolbar like the Tk backend instead of as a status line at the bottom of the widget. 4) Changed the toolbar pixmaps to use the ppm files instead of the png files. I noticed that the Tk backend buttons looked much nicer and it uses the ppm files so I switched them. 2005-06-17 Modified the gtk backend to not queue mouse motion events. This allows for live updates when dragging a slider. - CM 2005-06-17 Added starter CocoaAgg backend. Only works on OS 10.3 for now and requires PyObjC. (10.4 is high priority) - CM 2005-06-17 Upgraded pyparsing and applied Paul McGuire's suggestions for speeding things up. This more than doubles the speed of mathtext in my simple tests. JDH 2005-06-16 Applied David Cooke's subplot make_key patch ======================================================== 2005-06-15 0.82 released 2005-06-15 Added subplot config tool to GTK* backends -- note you must now import the NavigationToolbar2 from your backend of choice rather than from backend_gtk because it needs to know about the backend specific canvas -- see examples/embedding_in_gtk2.py. Ditto for wx backend -- see examples/embedding_in_wxagg.py 2005-06-15 backend_cairo.py: updated to use pycairo 0.5.0 - SC 2005-06-14 Wrote some GUI neutral widgets (Button, Slider, RadioButtons, CheckButtons) in matplotlib.widgets. See examples/widgets/*.py - JDH 2005-06-14 Exposed subplot parameters as rc vars and as the fig SubplotParams instance subplotpars. See figure.SubplotParams, figure.Figure.subplots_adjust and the pylab method subplots_adjust and examples/subplots_adjust.py . Also added a GUI neutral widget for adjusting subplots, see examples/subplot_toolbar.py - JDH 2005-06-13 Exposed cap and join style for lines with new rc params and line properties lines.dash_joinstyle : miter # miter|round|bevel lines.dash_capstyle : butt # butt|round|projecting lines.solid_joinstyle : miter # miter|round|bevel lines.solid_capstyle : projecting # butt|round|projecting 2005-06-13 Added kwargs to Axes init 2005-06-13 Applied Baptiste's tick patch - JDH 2005-06-13 Fixed rc alias 'l' bug reported by Fernando by removing aliases for mainlevel rc options. - JDH 2005-06-10 Fixed bug #1217637 in ticker.py - DSD 2005-06-07 Fixed a bug in texmanager.py: .aux files not being removed - DSD 2005-06-08 Added Sean Richard's hist binning fix -- see API_CHANGES - JDH 2005-06-07 Fixed a bug in texmanager.py: .aux files not being removed - DSD ===================================================================== 2005-06-07 matplotlib-0.81 released 2005-06-06 Added autoscale_on prop to axes 2005-06-06 Added Nick's picker "among" patch - JDH 2005-06-05 Fixed a TeX/LaTeX font discrepency in backend_ps. - DSD 2005-06-05 Added a ps.distill option in rc settings. If True, postscript output will be distilled using ghostscript, which should trim the file size and allow it to load more quickly. Hopefully this will address the issue of large ps files due to font definitions. Tested with gnu-ghostscript-8.16. - DSD 2005-06-03 Improved support for tex handling of text in backend_ps. - DSD 2005-06-03 Added rc options to render text with tex or latex, and to select the latex font package. - DSD 2005-06-03 Fixed a bug in ticker.py causing a ZeroDivisionError 2005-06-02 backend_gtk.py remove DBL_BUFFER, add line to expose_event to try to fix pygtk 2.6 redraw problem - SC 2005-06-01 The default behavior of ScalarFormatter now renders scientific notation and large numerical offsets in a label at the end of the axis. - DSD 2005-06-01 Added Nicholas' frombyte image patch - JDH 2005-05-31 Added vertical TeX support for agg - JDH 2005-05-31 Applied Eric's cntr patch - JDH 2005-05-27 Finally found the pesky agg bug (which Maxim was kind enough to fix within hours) that was causing a segfault in the win32 cached marker drawing. Now windows users can get the enormouse performance benefits of caced markers w/o those occasional pesy screenshots. - JDH 2005-05-27 Got win32 build system working again, using a more recent version of gtk and pygtk in the win32 build, gtk 2.6 from http://www.gimp.org/~tml/gimp/win32/downloads.html (you will also need libpng12.dll to use these). I haven't tested whether this binary build of mpl for win32 will work with older gtk runtimes, so you may need to upgrade. 2005-05-27 Fixed bug where 2nd wxapp could be started if using wxagg backend. - ADS 2005-05-26 Added Daishi text with dash patch -- see examples/dashtick.py 2005-05-26 Moved backend_latex functionality into backend_ps. If text.usetex=True, the PostScript backend will use LaTeX to generate the .ps or .eps file. Ghostscript is required for eps output. - DSD 2005-05-24 Fixed alignment and color issues in latex backend. - DSD 2005-05-21 Fixed raster problem for small rasters with dvipng -- looks like it was a premultipled alpha problem - JDH 2005-05-20 Added linewidth and faceted kwarg to scatter to control edgewidth and color. Also added autolegend patch to inspect line segments. 2005-05-18 Added Orsay and JPL qt fixes - JDH 2005-05-17 Added a psfrag latex backend -- some alignment issues need to be worked out. Run with -dLaTeX and a *.tex file and *.eps file are generated. latex and dvips the generated latex file to get ps output. Note xdvi *does* not work, you must generate ps.- JDH 2005-05-13 Added Florent Rougon's Axis set_label1 patch 2005-05-17 pcolor optimization, fixed bug in previous pcolor patch - JSWHIT 2005-05-16 Added support for masked arrays in pcolor - JSWHIT 2005-05-12 Started work on TeX text for antigrain using pngdvi -- see examples/tex_demo.py and the new module matplotlib.texmanager. Rotated text not supported and rendering small glyps is not working right yet. BUt large fontsizes and/or high dpi saved figs work great. 2005-05-10 New image resize options interpolation options. New values for the interp kwarg are 'nearest', 'bilinear', 'bicubic', 'spline16', 'spline36', 'hanning', 'hamming', 'hermite', 'kaiser', 'quadric', 'catrom', 'gaussian', 'bessel', 'mitchell', 'sinc', 'lanczos', 'blackman' See help(imshow) for details, particularly the interpolation, filternorm and filterrad kwargs 2005-05-10 Applied Eric's contour mem leak fixes - JDH 2005-05-10 Extended python agg wrapper and started implementing backend_agg2, an agg renderer based on the python wrapper. This will be more flexible and easier to extend than the current backend_agg. See also examples/agg_test.py - JDH 2005-05-09 Added Marcin's no legend patch to exclude lines from the autolegend builder plot(x, y, label='nolegend') 2005-05-05 Upgraded to agg23 2005-05-05 Added newscalarformatter_demo.py to examples. -DSD 2005-05-04 Added NewScalarFormatter. Improved formatting of ticklabels, scientific notation, and the ability to plot large large numbers with small ranges, by determining a numerical offset. See ticker.NewScalarFormatter for more details. -DSD 2005-05-03 Added the option to specify a delimiter in pylab.load -DSD 2005-04-28 Added Darren's line collection example 2005-04-28 Fixed aa property in agg - JDH 2005-04-27 Set postscript page size in .matplotlibrc - DSD 2005-04-26 Added embedding in qt example. - JDH 2005-04-14 Applied Michael Brady's qt backend patch: 1) fix a bug where keyboard input was grabbed by the figure and not released 2) turn on cursor changes 3) clean up a typo and commented-out print statement. - JDH 2005-04-14 Applied Eric Firing's masked data lines patch and contour patch. Support for masked arrays has been added to the plot command and to the Line2D object. Only the valid points are plotted. A "valid_only" kwarg was added to the get_xdata() and get_ydata() methods of Line2D; by default it is False, so that the original data arrays are returned. Setting it to True returns the plottable points. - see examples/masked_demo.py - JDH 2005-04-13 Applied Tim Leslie's arrow key event handling patch - JDH ================================================================= 0.80 released 2005-04-11 Applied a variant of rick's xlim/ylim/axis patch. These functions now take kwargs to let you selectively alter only the min or max if desired. Eg xlim(xmin=2) or axis(ymax=3). They always return the new lim. - JDH 2005-04-11 Incorporated Werner's wx patch -- wx backend should be compatible with wxpython2.4 and recent versions of 2.5. Some early versions of wxpython 2.5 will not work because there was a temporary change in the dc API that was rolled back to make it 2.4 compliant 2005-04-11 modified tkagg show so that new figure window pops up on call to figure 2005-04-11 fixed wxapp init bug 2005-04-02 updated backend_ps.draw_lines, draw_markers for use with the new API - DSD 2005-04-01 Added editable polygon example ========================================================================== 2005-03-31 0.74 released 2005-03-30 Fixed and added checks for floating point inaccuracy in ticker.Base - DSD 2005-03-30 updated /ellipse definition in backend_ps.py to address bug #1122041 - DSD 2005-03-29 Added unicode support for Agg and PS - JDH 2005-03-28 Added Jarrod's svg patch for text - JDH 2005-03-28 Added Ludal's arrow and quiver patch - JDH 2005-03-28 Added label kwarg to Axes to facilitate forcing the creation of new Axes with otherwise identical attributes 2005-03-28 Applied boxplot and OSX font search patches 2005-03-27 Added ft2font NULL check to fix Japanase font bug - JDH 2005-03-27 Added sprint legend patch plus John Gill's tests and fix -- see examples/legend_auto.py - JDH ========================================================================== 2005-03-19 0.73.1 released 2005-03-19 Reverted wxapp handling because it crashed win32 - JDH 2005-03-18 Add .number attribute to figure objects returned by figure() - FP =========================================================================== 2005-03-18 0.73 released 2005-03-16 Fixed labelsep bug 2005-03-16 Applied Darren's ticker fix for small ranges - JDH 2005-03-16 Fixed tick on horiz colorbar - JDH 2005-03-16 Added Japanses winreg patch - JDH 2005-03-15 backend_gtkagg.py: changed to use double buffering, this fixes the problem reported Joachim Berdal Haga - "Parts of plot lagging from previous frame in animation". Tested with anim.py and it makes no noticable difference to performance (23.7 before, 23.6 after) - SC 2005-03-14 add src/_backend_gdk.c extension to provide a substitute function for pixbuf.get_pixels_array(). Currently pixbuf.get_pixels_array() only works with Numeric, and then only works if pygtk has been compiled with Numeric support. The change provides a function pixbuf_get_pixels_array() which works with Numeric and numarray and is always available. It means that backend_gtk should be able to display images and mathtext in all circumstances. - SC 2005-03-11 Upgraded CXX to 5.3.1 2005-03-10 remove GraphicsContextPS.set_linestyle() and GraphicsContextSVG.set_linestyle() since they do no more than the base class GraphicsContext.set_linestyle() - SC 2005-03-09 Refactored contour functionality into dedicated module 2005-03-09 Added Eric's contourf updates and Nadia's clabel functionality 2005-03-09 Moved colorbar to figure.Figure to expose it for API developers - JDH 2005-03-09 backend_cairo.py: implemented draw_markers() - SC 2005-03-09 cbook.py: only use enumerate() (the python version) if the builtin version is not available. Add new function 'izip' which is set to itertools.izip if available and the python equivalent if not available. - SC 2005-03-07 backend_gdk.py: remove PIXELS_PER_INCH from points_to_pixels(), but still use it to adjust font sizes. This allows the GTK version of line_styles.py to more closely match GTKAgg, previously the markers were being drawn too large. - SC 2005-03-01 Added Eric's contourf routines 2005-03-01 Added start of proper agg SWIG wrapper. I would like to expose agg functionality directly a the user level and this module will serve that purpose eventually, and will hopefully take over most of the functionality of the current _image and _backend_agg modules. - JDH 2005-02-28 Fixed polyfit / polyval to convert input args to float arrays - JDH 2005-02-25 Add experimental feature to backend_gtk.py to enable/disable double buffering (DBL_BUFFER=True/False) - SC 2005-02-24 colors.py change ColorConverter.to_rgb() so it always returns rgb (and not rgba), allow cnames keys to be cached, change the exception raised from RuntimeError to ValueError (like hex2color()) hex2color() use a regular expression to check the color string is valid - SC 2005-02-23 Added rc param ps.useafm so backend ps can use native afm fonts or truetype. afme breaks mathtext but causes much smaller font sizes and may result in images that display better in some contexts (eg pdfs incorporated into latex docs viewed in acrobat reader). I would like to extend this approach to allow the user to use truetype only for mathtext, which should be easy. 2005-02-23 Used sequence protocol rather than tuple in agg collection drawing routines for greater flexibility - JDH =========================================================== 2005-02-22 0.72.1 released 2005-02-21 fixed linestyles for collections -- contour now dashes for levels <0 2005-02-21 fixed ps color bug - JDH 2005-02-15 fixed missing qt file 2005-02-15 banished error_msg and report_error. Internal backend methods like error_msg_gtk are preserved. backend writers, check your backends, and diff against 0.72 to make sure I did the right thing! - JDH 2005-02-14 Added enthought traits to matplotlib tree - JDH =========================================================== 2005-02-14 0.72 released 2005-02-14 fix bug in cbook alltrue() and onetrue() - SC 2005-02-11 updated qtagg backend from Ted - JDH 2005-02-11 matshow fixes for figure numbering, return value and docs - FP 2005-02-09 new zorder example for fine control in zorder_demo.py - FP 2005-02-09 backend renderer draw_lines now has transform in backend, as in draw_markers; use numerix in _backend_agg, aded small line optimization to agg 2005-02-09 subplot now deletes axes that it overlaps 2005-02-08 Added transparent support for gzipped files in load/save - Fernando Perez (FP from now on). 2005-02-08 Small optimizations in PS backend. They may have a big impact for large plots, otherwise they don't hurt - FP 2005-02-08 Added transparent support for gzipped files in load/save - Fernando Perez (FP from now on). 2005-02-07 Added newstyle path drawing for markers - only implemented in agg currently - JDH 2005-02-05 Some superscript text optimizations for ticking log plots 2005-02-05 Added some default key press events to pylab figures: 'g' toggles grid - JDH 2005-02-05 Added some support for handling log switching for lines that have nonpos data - JDH 2005-02-04 Added Nadia's contour patch - contour now has matlab compatible syntax; this also fixed an unequal sized contour array bug- JDH 2005-02-04 Modified GTK backends to allow the FigureCanvas to be resized smaller than its original size - SC 2005-02-02 Fixed a bug in dates mx2num - JDH 2005-02-02 Incorporated Fernando's matshow - JDH 2005-02-01 Added Fernando's figure num patch, including experemental support for pylab backend switching, LineCOllection.color warns, savefig now a figure method, fixed a close(fig) bug - JDH 2005-01-31 updated datalim in contour - JDH 2005-01-30 Added backend_qtagg.py provided by Sigve Tjora - SC 2005-01-28 Added tk.inspect rc param to .matplotlibrc. IDLE users should set tk.pythoninspect:True and interactive:True and backend:TkAgg 2005-01-28 Replaced examples/interactive.py with an updated script from Fernando Perez - SC 2005-01-27 Added support for shared x or y axes. See examples/shared_axis_demo.py and examples/ganged_plots.py 2005-01-27 Added Lee's patch for missing symbols \leq and \LEFTbracket to _mathtext_data - JDH 2005-01-26 Added Baptiste's two scales patch -- see help(twinx) in the pylab interface for more info. See also examples/two_scales.py 2005-01-24 Fixed a mathtext parser bug that prevented font changes in sub/superscripts - JDH 2005-01-24 Fixed contour to work w/ interactive changes in colormaps, clim, etc - JDH =============================================================== 2005-01-21 matplotlib-0.71 released 2005-01-21 Refactored numerix to solve vexing namespace issues - JDH 2005-01-21 Applied Nadia's contour bug fix - JDH 2005-01-20 Made some changes to the contour routine - particularly region=1 seems t fix a lot of the zigzag strangeness. Added colormaps as default for contour - JDH 2005-01-19 Restored builtin names which were overridden (min, max, abs, round, and sum) in pylab. This is a potentially significant change for those who were relying on an array version of those functions that previously overrode builtin function names. - ADS 2005-01-18 Added accents to mathtext: \hat, \breve, \grave, \bar, \acute, \tilde, \vec, \dot, \ddot. All of them have the same syntax, eg to make an overbar you do \bar{o} or to make an o umlaut you do \ddot{o}. The shortcuts are also provided, eg: \"o \'e \`e \~n \.x \^y - JDH 2005-01-18 Plugged image resize memory leaks - JDH 2005-01-18 Fixed some mathtext parser problems relating to superscripts 2005-01-17 Fixed a yticklabel problem for colorbars under change of clim - JDH 2005-01-17 Cleaned up Destroy handling in wx reducing memleak/fig from approx 800k to approx 6k- JDH 2005-01-17 Added kappa to latex_to_bakoma - JDH 2005-01-15 Support arbitrary colorbar axes and horizontal colorbars - JDH 2005-01-15 Fixed colormap number of colors bug so that the colorbar has the same discretization as the image - JDH 2005-01-15 Added Nadia's x,y contour fix - JDH 2005-01-15 backend_cairo: added PDF support which requires pycairo 0.1.4. Its not usable yet, but is ready for when the Cairo PDF backend matures - SC 2005-01-15 Added Nadia's x,y contour fix 2005-01-12 Fixed set clip_on bug in artist - JDH 2005-01-11 Reverted pythoninspect in tkagg - JDH 2005-01-09 Fixed a backend_bases event bug caused when an event is triggered when location is None - JDH 2005-01-07 Add patch from Stephen Walton to fix bug in pylab.load() when the % character is included in a comment. - ADS 2005-01-07 Added markerscale attribute to Legend class. This allows the marker size in the legend to be adjusted relative to that in the plot. - ADS 2005-01-06 Add patch from Ben Vanhaeren to make the FigureManagerGTK vbox a public attribute - SC ==================================================================== 2004-12-30 Release 0.70 2004-12-28 Added coord location to key press and added a examples/picker_demo.py 2004-12-28 Fixed coords notification in wx toolbar - JDH 2004-12-28 Moved connection and disconnection event handling to the FigureCanvasBase. Backends now only need to connect one time for each of the button press, button release and key press/release functions. The base class deals with callbacks and multiple connections. This fixes flakiness on some backends (tk, wx) in the presence of multiple connections and/or disconnect - JDH 2004-12-27 Fixed PS mathtext bug where color was not set - Jochen please verify correct - JDH 2004-12-27 Added Shadow class and added shadow kwarg to legend and pie for shadow effect - JDH 2004-12-27 Added pie charts and new example/pie_demo.py 2004-12-23 Fixed an agg text rotation alignment bug, fixed some text kwarg processing bugs, and added examples/text_rotation.py to explain and demonstrate how text rotations and alignment work in matplotlib. - JDH ====================================================================== 2004-12-22 0.65.1 released - JDH 2004-12-22 Fixed colorbar bug which caused colorbar not to respond to changes in colormap in some instances - JDH 2004-12-22 Refactored NavigationToolbar in tkagg to support app embedding , init now takes (canvas, window) rather than (canvas, figman) - JDH 2004-12-21 Refactored axes and subplot management - removed add_subplot and add_axes from the FigureManager. classic toolbar updates are done via an observer pattern on the figure using add_axobserver. Figure now maintains the axes stack (for gca) and supports axes deletion. Ported changes to GTK, Tk, Wx, and FLTK. Please test! Added delaxes - JDH 2004-12-21 Lots of image optimizations - 4x performance boost over 0.65 JDH 2004-12-20 Fixed a figimage bug where the axes is shown and modified tkagg to move the destroy binding into the show method. 2004-12-18 Minor refactoring of NavigationToolbar2 to support embedding in an application - JDH 2004-12-14 Added linestyle to collections (currently broken) - JDH 2004-12-14 Applied Nadia's setupext patch to fix libstdc++ link problem with contour and solaris -JDH 2004-12-14 A number of pychecker inspired fixes, including removal of True and False from cbook which I erroneously thought was needed for python2.2 - JDH 2004-12-14 Finished porting doc strings for set introspection. Used silent_list for many get funcs that return lists. JDH 2004-12-13 dates.py: removed all timezone() calls, except for UTC - SC ====================================================================== 2004-12-13 0.65 released - JDH 2004-12-13 colors.py: rgb2hex(), hex2color() made simpler (and faster), also rgb2hex() - added round() instead of integer truncation hex2color() - changed 256.0 divisor to 255.0, so now '#ffffff' becomes (1.0,1.0,1.0) not (0.996,0.996,0.996) - SC 2004-12-11 Added ion and ioff to pylab interface - JDH 2004-12-11 backend_template.py: delete FigureCanvasTemplate.realize() - most backends don't use it and its no longer needed backend_ps.py, backend_svg.py: delete show() and draw_if_interactive() - they are not needed for image backends backend_svg.py: write direct to file instead of StringIO - SC 2004-12-10 Added zorder to artists to control drawing order of lines, patches and text in axes. See examples/zoder_demo.py - JDH 2004-12-10 Fixed colorbar bug with scatter - JDH 2004-12-10 Added Nadia Dencheva <dencheva@stsci.edu> contour code - JDH 2004-12-10 backend_cairo.py: got mathtext working - SC 2004-12-09 Added Norm Peterson's svg clipping patch 2004-12-09 Added Matthew Newville's wx printing patch 2004-12-09 Migrated matlab to pylab - JDH 2004-12-09 backend_gtk.py: split into two parts - backend_gdk.py - an image backend - backend_gtk.py - A GUI backend that uses GDK - SC 2004-12-08 backend_gtk.py: remove quit_after_print_xvfb(*args), show_xvfb(), Dialog_MeasureTool(gtk.Dialog) one month after sending mail to matplotlib-users asking if anyone still uses these functions - SC 2004-12-02 backend_bases.py, backend_template.py: updated some of the method documentation to make them consistent with each other - SC 2004-12-04 Fixed multiple bindings per event for TkAgg mpl_connect and mpl_disconnect. Added a "test_disconnect" command line parameter to coords_demo.py JTM 2004-12-04 Fixed some legend bugs JDH 2004-11-30 Added over command for oneoff over plots. Eg over(plot, x, y, lw=2). Works with any plot function. 2004-11-30 Added bbox property to text - JDH 2004-11-29 Zoom to rect now respect reversed axes limits (for both linear and log axes). - GL 2004-11-29 Added the over command to the matlab interface. over allows you to add an overlay plot regardless of hold state. - JDH 2004-11-25 Added Printf to mplutils for printf style format string formatting in C++ (should help write better exceptions) 2004-11-24 IMAGE_FORMAT: remove from agg and gtkagg backends as its no longer used - SC 2004-11-23 Added matplotlib compatible set and get introspection. See set_and_get.py 2004-11-23 applied Norbert's patched and exposed legend configuration to kwargs - JDH 2004-11-23 backend_gtk.py: added a default exception handler - SC 2004-11-18 backend_gtk.py: change so that the backend knows about all image formats and does not need to use IMAGE_FORMAT in other backends - SC 2004-11-18 Fixed some report_error bugs in string interpolation as reported on SF bug tracker- JDH 2004-11-17 backend_gtkcairo.py: change so all print_figure() calls render using Cairo and get saved using backend_gtk.print_figure() - SC 2004-11-13 backend_cairo.py: Discovered the magic number (96) required for Cairo PS plots to come out the right size. Restored Cairo PS output and added support for landscape mode - SC 2004-11-13 Added ishold - JDH 2004-11-12 Added many new matlab colormaps - autumn bone cool copper flag gray hot hsv jet pink prism spring summer winter - PG 2004-11-11 greatly simplify the emitted postscript code - JV 2004-11-12 Added new plotting functions spy, spy2 for sparse matrix visualization - JDH 2004-11-11 Added rgrids, thetragrids for customizing the grid locations and labels for polar plots - JDH 2004-11-11 make the Gtk backends build without an X-server connection - JV 2004-11-10 matplotlib/__init__.py: Added FROZEN to signal we are running under py2exe (or similar) - is used by backend_gtk.py - SC 2004-11-09 backend_gtk.py: Made fix suggested by maffew@cat.org.au to prevent problems when py2exe calls pygtk.require(). - SC 2004-11-09 backend_cairo.py: Added support for printing to a fileobject. Disabled cairo PS output which is not working correctly. - SC ============================================================== 2004-11-08 matplotlib-0.64 released 2004-11-04 Changed -dbackend processing to only use known backends, so we don't clobber other non-matplotlib uses of -d, like -debug. 2004-11-04 backend_agg.py: added IMAGE_FORMAT to list the formats that the backend can save to. backend_gtkagg.py: added support for saving JPG files by using the GTK backend - SC 2004-10-31 backend_cairo.py: now produces png and ps files (although the figure sizing needs some work). pycairo did not wrap all the necessary functions, so I wrapped them myself, they are included in the backend_cairo.py doc string. - SC 2004-10-31 backend_ps.py: clean up the generated PostScript code, use the PostScript stack to hold itermediate values instead of storing them in the dictionary. - JV 2004-10-30 backend_ps.py, ft2font.cpp, ft2font.h: fix the position of text in the PostScript output. The new FT2Font method get_descent gives the distance between the lower edge of the bounding box and the baseline of a string. In backend_ps the text is shifted upwards by this amount. - JV 2004-10-30 backend_ps.py: clean up the code a lot. Change the PostScript output to be more DSC compliant. All definitions for the generated PostScript are now in a PostScript dictionary 'mpldict'. Moved the long comment about drawing ellipses from the PostScript output into a Python comment. - JV 2004-10-30 backend_gtk.py: removed FigureCanvasGTK.realize() as its no longer needed. Merged ColorManager into GraphicsContext backend_bases.py: For set_capstyle/joinstyle() only set cap or joinstyle if there is no error. - SC 2004-10-30 backend_gtk.py: tidied up print_figure() and removed some of the dependency on widget events - SC 2004-10-28 backend_cairo.py: The renderer is complete except for mathtext, draw_image() and clipping. gtkcairo works reasonably well. cairo does not yet create any files since I can't figure how to set the 'target surface', I don't think pycairo wraps the required functions - SC 2004-10-28 backend_gtk.py: Improved the save dialog (GTK 2.4 only) so it presents the user with a menu of supported image formats - SC 2004-10-28 backend_svg.py: change print_figure() to restore original face/edge color backend_ps.py : change print_figure() to ensure original face/edge colors are restored even if there's an IOError - SC 2004-10-27 Applied Norbert's errorbar patch to support barsabove kwarg 2004-10-27 Applied Norbert's legend patch to support None handles 2004-10-27 Added two more backends: backend_cairo.py, backend_gtkcairo.py They are not complete yet, currently backend_gtkcairo just renders polygons, rectangles and lines - SC 2004-10-21 Added polar axes and plots - JDH 2004-10-20 Fixed corrcoef bug exposed by corrcoef(X) where X is matrix - JDH 2004-10-19 Added kwarg support to xticks and yticks to set ticklabel text properties -- thanks to T. Edward Whalen for the suggestion 2004-10-19 Added support for PIL images in imshow(), image.py - ADS 2004-10-19 Re-worked exception handling in _image.py and _transforms.py to avoid masking problems with shared libraries. - JTM 2004-10-16 Streamlined the matlab interface wrapper, removed the noplot option to hist - just use mlab.hist instead. 2004-09-30 Added Andrew Dalke's strftime code to extend the range of dates supported by the DateFormatter - JDH 2004-09-30 Added barh - JDH 2004-09-30 Removed fallback to alternate array package from numerix so that ImportErrors are easier to debug.

SC 2004-09-30 Made some changes to support python22 - lots of doc fixes. - JDH 2004-09-29 Added a Verbose class for reporting - JDH ============================================================== 2004-09-28 Released 0.63.0 2004-09-28 Added save to file object for agg - see examples/print_stdout.py 2004-09-24 Reorganized all py code to lib subdir 2004-09-24 Fixed axes resize image edge effects on interpolation - required upgrade to agg22 which fixed an agg bug related to this problem 2004-09-20 Added toolbar2 message display for backend_tkagg. JTM 2004-09-17 Added coords formatter attributes. These must be callable, and return a string for the x or y data. These will be used to format the x and y data for the coords box. Default is the axis major formatter. Eg # format the coords message box def price(x): return '$%1.2f'%x ax.format_xdata = DateFormatter('%Y-%m-%d') ax.format_ydata = price 2004-09-17 Total rewrite of dates handling to use python datetime with num2date, date2num and drange. pytz for timezone handling, dateutils for spohisticated ticking. date ranges from 0001-9999 are supported. rrules allow arbitrary date ticking. examples/date_demo*.py converted to show new usage. new example examples/date_demo_rrule.py shows how to use rrules in date plots. The date locators are much more general and almost all of them have different constructors. See matplotlib.dates for more info. 2004-09-15 Applied Fernando's backend __init__ patch to support easier backend maintenance. Added his numutils to mlab. JDH 2004-09-16 Re-designated all files in matplotlib/images as binary and w/o keyword substitution using "cvs admin -kb *.svg ...". See binary files in "info cvs" under Linux. This was messing up builds from CVS on windows since CVS was doing lf -> cr/lf and keyword substitution on the bitmaps. - JTM 2004-09-15 Modified setup to build array-package-specific extensions for those extensions which are array-aware. Setup builds extensions automatically for either Numeric, numarray, or both, depending on what you have installed. Python proxy modules for the array-aware extensions import the version optimized for numarray or Numeric determined by numerix. - JTM 2004-09-15 Moved definitions of infinity from mlab to numerix to avoid divide by zero warnings for numarray - JTM 2004-09-09 Added axhline, axvline, axhspan and axvspan ============================================================== 2004-08-30 matplotlib 0.62.4 released 2004-08-30 Fixed a multiple images with different extent bug, Fixed markerfacecolor as RGB tuple 2004-08-27 Mathtext now more than 5x faster.

Lots to do -- get crackin'! - Fixed y zoom tool bug - Adopted a compromise fix for the y data clipping problem. The problem was that for solid lines, the y data clipping (as opposed to the gc clipping) caused artifactual horizontal solid lines near the ylim boundaries. I did a 5% offset hack in Axes set_ylim functions which helped, but didn't cure the problem for very high gain y zooms. So I disabled y data clipping for connected lines . If you need extensive y clipping, either plot(y,x) because x data clipping is always enabled, or change the _set_clip code to 'if 1' as indicated in the lines.py src. See _set_clip in lines.py and set_ylim in figure.py for more information. 2002-12-11 - Added a measurement dialog to the figure window to measure axes position and the delta x delta y with a left mouse drag. These defaults can be overridden by deriving from Figure and overrriding button_press_event, button_release_event, and motion_notify_event, and _dialog_measure_tool. - fixed the navigation dialog so you can check the axes the navigation buttons apply to. 2003-04-23 Released matplotlib v0.1 2003-04-24 Added a new line style PixelLine2D which is the plots the markers as pixels (as small as possible) with format symbol ',' Added a new class Patch with derived classes Rectangle, RegularPolygon and Circle 2003-04-25 Implemented new functions errorbar, scatter and hist Added a new line type '|' which is a vline. syntax is plot(x, Y, '|') where y.shape = len(x),2 and each row gives the ymin,ymax for the respective values of x. Previously I had implemented vlines as a list of lines, but I needed the efficientcy of the numeric clipping for large numbers of vlines outside the viewport, so I wrote a dedicated class Vline2D which derives from Line2D 2003-05-01 Fixed ytick bug where grid and tick show outside axis viewport with gc clip 2003-05-14 Added new ways to specify colors 1) matlab format string 2) html-style hex string, 3) rgb tuple. See examples/color_demo.py 2003-05-28 Changed figure rendering to draw form a pixmap to reduce flicker. See examples/system_monitor.py for an example where the plot is continusouly updated w/o flicker. This example is meant to simulate a system monitor that shows free CPU, RAM, etc... 2003-08-04 Added Jon Anderson's GTK shell, which doesn't require pygtk to have threading built-in and looks nice! 2003-08-25 Fixed deprecation warnings for python2.3 and pygtk-1.99.18 2003-08-26 Added figure text with new example examples/figtext.py 2003-08-27 Fixed bugs i figure text with font override dictionairies and fig text that was placed outside the window bounding box 2003-09-1 thru 2003-09-15 Added a postscript and a GD module backend 2003-09-16 Fixed font scaling and point scaling so circles, squares, etc on lines will scale with DPI as will fonts. Font scaling is not fully implemented on the gtk backend because I have not figured out how to scale fonts to arbitrary sizes with GTK 2003-09-17 Fixed figure text bug which crashed X windows on long figure text extending beyond display area. This was, I believe, due to the vestigial erase functionality that was no longer needed since I began rendering to a pixmap 2003-09-30 Added legend 2003-10-01 Fixed bug when colors are specified with rgb tuple or hex string. 2003-10-21 Andrew Straw provided some legend code which I modified and incorporated. Thanks Andrew! 2003-10-27 Fixed a bug in axis.get_view_distance that affected zoom in versus out with interactive scrolling, and a bug in the axis text reset system that prevented the text from being redrawn on a interactive gtk view lim set with the widget Fixed a bug in that prevented the manual setting of ticklabel strings from working properly 2003-11-02 - Do a nearest neighbor color pick on GD when allocate fails 2003-11-02 - Added pcolor plot - Added MRI example - Fixed bug that screwed up label position if xticks or yticks were empty - added nearest neighbor color picker when GD max colors exceeded - fixed figure background color bug in GD backend 2003-11-10 - 2003-11-11 - major refactoring. * Ticks (with labels, lines and grid) handled by dedicated class * Artist now know bounding box and dpi * Bounding boxes and transforms handled by dedicated classes * legend in dedicated class. Does a better job of alignment and bordering. Can be initialized with specific line instances. See examples/legend_demo2.py 2003-11-14 Fixed legend positioning bug and added new position args 2003-11-16 Finsihed porting GD to new axes API 2003-11-20 - add TM for matlab on website and in docs 2003-11-20 - make a nice errorbar and scatter screenshot 2003-11-20 - auto line style cycling for multiple line types broken 2003-11-18 (using inkrect) :logical rect too big on gtk backend 2003-11-18 ticks don't reach edge of axes in gtk mode -- rounding error? 2003-11-20 - port Gary's errorbar code to new API before 0.40 2003-11-20 - problem with stale _set_font. legend axes box doesn't resize on save in GTK backend -- see htdocs legend_demo.py 2003-11-21 - make a dash-dot dict for the GC 2003-12-15 - fix install path bug
