A new release of matplotlib is posted to the sourceforge download site http://sourceforge.net/project/showfiles.php?group_id=80706
You can read the release notes with links at http://matplotlib.sourceforge.net/whats_new.html enhanced mathtext - Complete revamp of matplotlib's internal math layout and rendering engine. Michael Droetboom has improved the TeX parser to significantly expand it's coverege, and implemeted Knuth's box layout algorithms. Additionally, the much anticipated STIX fonts for math expressions have come online and ship with matplotlib. See a sample of the new mathtext at http://matplotlib.sourceforge.net/screenshots.html#mathtext_examples better configuration - Darren Dale has provided support for a site.cfg configuration file to enable users and package maintainers to have better control over the matplotlib build process. He has also provided a (currently optional) enthought.traits enabled property configuration to replace matplotlib's rc configuration using a maplotlib.conf file writing to file-like objects - You can now pass file like objects (eg StringIO) to all backends for hardcopy. This has been a much requested feature for usage in web application servers. record array support - New functions for loading, displaying and saving numpy record arrays in matplotlib.mlab. See for example, http://matplotlib.sourceforge.net/examples/loadrec.py pyplot - Added a module matplotlib.pyplot which has all of pylab's plotting functions (eg figure, plot, show, close) but does not import the numpy namepace. This is useful for those who want to use the pylab functionality w/o the namespace clutter. http://matplotlib.sourceforge.net/matplotlib.pyplot.html maskedarray - Added optional support for the scipy sandbox masked array packaged. Configurable with an rc setting. plotfile - Added new pylab/pyplot command plotfile for gnuplot style file plotting http://matplotlib.sourceforge.net/matplotlib.pyplot.html#-plotfile http://matplotlib.sourceforge.net/examples/plotfile_demo.py Here is the complete CHANGELOG =============================================================== 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 2007-10-24 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. Thank you Alexander Schmolck for contributing a patch - DSD 2007-07-17 added validation to setting and changing rcParams - DSD 2007-07-17 bugfix segfault in transforms module. Thanks Ben North for the patch. - ADS 2007-07-16 clean up some code in ticker.ScalarFormatter, use unicode to render multiplication sign in offset ticklabel - DSD 2007-07-16 fixed a formatting bug in ticker.ScalarFormatter's scientific notation (10^0 was being rendered as 10 in some cases) - DSD 2007-07-13 Add MPL_isfinite64() and MPL_isinf64() for testing doubles in (the now misnamed) MPL_isnan.h. - ADS 2007-07-13 The matplotlib._isnan module removed (use numpy.isnan) - ADS 2007-07-13 Some minor cleanups in _transforms.cpp - ADS 2007-07-13 Removed the rest of the numerix extension code detritus, numpified axes.py, and cleaned up the imports in axes.py - JDH 2007-07-13 Added legend.loc as configurable option that could in future default to 'best'. - NN 2007-07-12 Bugfixes in mlab.py to coerce inputs into numpy arrays. -ADS 2007-07-11 Added linespacing kwarg to text.Text - EF 2007-07-11 Added code to store font paths in SVG files. - MGD 2007-07-10 Store subset of TTF font as a Type 3 font in PDF files. - MGD 2007-07-09 Store subset of TTF font as a Type 3 font in PS files. - MGD 2007-07-09 Applied Paul's pick restructure pick and add pickers, sourceforge patch 1749829 - JDH 2007-07-09 Applied Allan's draw_lines agg optimization. JDH 2007-07-08 Applied Carl Worth's patch to fix cairo draw_arc - SC 2007-07-07 fixed bug 1712099: xpdf distiller on windows - DSD 2007-06-30 Applied patches to tkagg, gtk, and wx backends to reduce memory leakage. Patches supplied by Mike Droettboom; see tracker numbers 1745400, 1745406, 1745408. 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. (Thanks Tocer and also Werner Bruhin.) -ADS 2007-06-27 Added a scroll event to the mpl event handling system and implemented it for backends GTK* -- other backend users/developers/maintainers, please add support for your backend. - JDH 2007-06-25 Changed default to clip=False in colors.Normalize; modified ColorbarBase for easier colormap display - EF 2007-06-13 Added maskedarray option to rc, numerix - EF 2007-06-11 Python 2.5 compatibility fix for mlab.py - EF 2007-06-10 In matplotlibrc file, use 'dashed' | 'solid' instead of a pair of floats for contour.negative_linestyle - EF 2007-06-08 Allow plot and fill fmt string to be any mpl string colorspec - EF 2007-06-08 Added gnuplot file plotfile function to pylab -- see examples/plotfile_demo.py - JDH 2007-06-07 Disable build of numarray and Numeric extensions for internal MPL use and the numerix layer. - ADS 2007-06-07 Added csv2rec to matplotlib.mlab to support automatically converting csv files to record arrays using type introspection, and turned on native datetime support using the new units support in matplotlib.dates. See examples/loadrec.py ! JDH 2007-06-07 Simplified internal code of _auto_legend_data - NN 2007-06-04 Added labeldistance arg to Axes.pie to control the raidal distance of the wedge labels - JDH 2007-06-03 Turned mathtext in SVG into single <text> with multiple <tspan> objects (easier to edit in inkscape). - NN ------------------------------------------------------------------------- SF.Net email is sponsored by: The Future of Linux Business White Paper from Novell.
