This is the first bugfix release of the 0.98 series, with lots of
small bugs fixed and a few features added. Thanks to Charlie Moad for
the builds: src and binaries available from
http://sourceforge.net/project/showfiles.php?group_id=80706. For
those of you on the 0.91 maintenance branch, we have also put out a
0.91.4 bugfix release with downloads at the link above.

Greetings,
This is a friendly reminder that the Early Registration deadline for 
the EuroSciPy Conference is June 15th. If you're interested in 
attending, but have not yet registered, please visit:
http://www.scipy.org/EuroSciPy2008
The talks schedule is also now available there.
Also, the keynote speaker this year will be Travis Oliphant, the 
primary author of the recent NumPy rewrite. For those doing 
scientific computing using Python, this is a conference you'll not 
want to miss.
See you there.
Travis

matplotlib 0.98.0 is released
=============================
This is a milestone release of matplotlib with a significant internal
refactoring to support better transformations, path drawing, and
readily extensible coordinate projections and scales. Michael
Droettboom of STScI did the lion's share of the work, but a large
number of developers have made many significant contributions. This
is such a significant improvement of the matplotlib code base that we
are jumping from the 0.91 series to the 0.98 series, in anticipation
of rapid progress to 1.0.
Downloads are available at
http://sourceforge.net/project/platformdownload.php?group_id=80706
with binary installers for windows and OS X. Thanks to Charlie Moad
for the builds and release.
See the migration document at http://matplotlib.sf.net/MIGRATION.txt,
the API changes at http://matplotlib.sf.net/API_CHANGES, and the full
CHANGELOG at http://matplotlib.sf.net/CHANGELOG . You should manually
any old install of site-packages/matplotlib since the new version will
not properly install over it.
We've also done some work on the look and feel of the web site, with a
new logo an a less jarring color scheme, and are in the midst of a
fairly significant
documentation effort, so if you have any interest in writing documentation or
doing website design, join us on the developers list and ash how you can
contribute.
What's new in matplotlib 0.98
=============================
This is also available on the website at
http://matplotlib.sourceforge.net/whats_new.html
better transformations
----------------------
In what has been described as open-heart surgery on matplotlib,
Michael Droettboom, supported by STScI, has rewritten the transformation
infrastructure from the ground up, which not only makes the code more
intuitive, it supports custom user projections and scales. See
http://matplotlib.sf.net/doc/devel/add_new_projection.rst and
the http://matplotlib.sf.net/matplotlib.transforms.html module
documentation
proper paths
------------
For the first time, matplotlib supports spine paths across backends,
so you can pretty much draw anything. See the
http://matplotlib.sf.net/creenshots.html#path_patch_demo screenshot .
Thanks again to Michael Droettboom and STScI.
histogram enhancements
----------------------
hist can handle 2D arrays and create side-by-side or stacked
histograms, as well as cumulative filled and unfilled histograms
http://matplotlib.sf.net/examples/pylab/histogram_demo_extended.py
2D histogram hexbin
-------------------
2D hexagonal bin histogramming with optional log colorscales:
http://matplotlib.sourceforge.net/examples/pylab/hexbin_demo.py
ginput function
---------------
ginput (http://matplotlib.sf.net/matplotlib.pyplot.html#-ginput) is a
blocking function for interactive use to get input from the user. A
long requested feature submitted by Gael Varoquaux. See
http://matplotlib.sf.net/examples/pylab/ginput_demo.py.
image optimizations
-------------------
Enhancements to speed up color mapping and panning and zooming on dense images
better savefig
--------------
savefig (http://matplotlib.sf.net/matplotlib.pyplot.html#-savefig) now
supports save to file handles (great for web app servers) or unicode
filenames on all backends
record array functions
----------------------
some more helper functions to facilitate work with record arrays: rec_groupby,
rec2txt, and rec_summarize. These are found in matplotlib.mlab
(http://matplotlib.sf.net/matplotlib.mlab.html)
accurate elliptical arcs
------------------------
In support of the Phoenix mission to Mars, which used matplotlib in
ground tracking of the spacecraft, Michael Droettboom built on work by
Charlie Moad to provide an extremely accurate 8-spline approximation
to elliptical arcs (see
http://matplotlib.sf.net/matplotlib.patches.html#Arc-draw)win the
viewport. This provides a scale free, accurate graph of the arc
regardless of zoom level. See the screenshot and example at
http://matplotlib.sf.net/screenshots.html#ellipse_demo
imread enhanced
---------------
imread (http://matplotlib.sf.net/matplotlib.image.html#-imread) now
will use PIL when available to load images and return numpy arrays
backend enhancements
--------------------
* postscript : the postscript backend has clipping to paths (useful
for polar plots)
* PDF : the PDF backend handles composite glyphs properly, usetex fixes
* SVG : clip to path (useful for polar plots), inkscape cut-and-paste fixes.
* QT : Fixed a duplicate draw bug that slowed performance. Native qt
 toolbars and status bars used for the toolbar controls

matplotlib 0.91.3 is released
=============================
This is the maintenance bug-fix and feature enhancement release of the
0.91 branch. Because the 0.98 refactoring introduced more code
breakage than usual, we decided to branch the 0.91 series for users
unable to upgrade right away. We have ported as many bug fixes and
features to the maintenance branch as possible, and these are now
available for release as 0.91.3.
Homepage: http://matplotlib.sf.net
Downloads are available at
http://sourceforge.net/project/platformdownload.php?group_id=80706
with binary installers for windows and OS X. Thanks to Charlie Moad
for the builds and release.

Could someone tell me the difference between EPD and ETS ?
If I look at the summary, I see
 EPD = ETS + 10 other packages,
but 8 of the 10 other packages are already in ETS ???

Greetings,
Enthought is pleased to announce the release of the Enthought Python 
Distribution (EPD) version 2.5.2001.
http://www.enthought.com/epd
This release makes available both the RedHat 3.x (amd64) and Windows 
XP (x86) installers. OS X, Ubuntu and more (modern) RHEL versions are 
coming soon(!).
About EPD
---------
The Enthought Python Distribution is a "kitchen-sink-included" 
distribution of the Python Programming Language as well as over 60 
additional tools and libraries. It includes NumPy, SciPy, IPython, 2D 
and 3D visualization, database adapters and a lot of other tools right 
out of the box. Enthought is offering access to this bundle as a free 
service to academic and other non-profit organizations. We also offer 
an annual fee-based subscription service for Commercial and 
Governmental users to download and update the software bundle. 
(Everyone may try it out for free. Please see the License Information 
below.)
Included Software
-----------------
A short list includes:
Python 2.5.2, NumPy, SciPy, Traits, Mayavi, Chaco, Kiva, Enable, 
Matplotlib, wxPython and VTK.
The complete list of software with version numbers is available here:
http://www.enthought.com/products/epdlibraries.php
License Information
-------------------
EPD is a bundle of software, every piece of which is available 
separately for free under various open-source licenses. Not-for- 
profit, private-sector access to the bundle and its updates is, and 
will remain, free under the terms of the Subscription Agreement (see http://www.enthought.com/products/epdlicense.php 
 ). Commercial and Governmental users may try the bundle for free 
for 30 days. After the trial period, users may purchase a one-year 
subscription to download and update the bundle. Downloaded software 
obtained under the subscription agreement may be used by the 
subscriber in perpetuity.
This model should sound familiar, as our commercial offering is quite 
similar to the business model of a certain linux distributor. More 
information is also available in the FAQ ( http://www.enthought.com/products/epdfaq.php 
 ). For larger deployments, or those with special build or 
distribution needs, an Enterprise Subscription is also available.
Thanks
------
EPD is compelling because it solves a thorny packaging and 
distribution problem, but also because of the libraries which it 
includes. The folks here at Enthought would like to thank the Python 
developer community and the wider community that authors and 
contributes to these included libraries. We put these things to work 
every day and would be much less productive without them. So, thanks!

Travis,
A great initiative! I will attend and will submit an abstract of a
presentation on SimPy (Simulation in Python) and how this project will be
brought closer to SciPy.
Any idea where in Leipzig the conference will be held? I want to book a
hotel in the vicinity of the conference site.

We have uploaded source and binary releases of matplotlib-0.91.2 to
http://sourceforge.net/project/showfiles.php?group_id=80706&package_id=82474&release_id=566411.
Thanks to Charlie Moad for doing the release.
This is a bugfix release and includes several important fixes listed
below.
2008年01月06日 Released 0.91.2 at revision 4802
2007年12月26日 Reduce too-late use of matplotlib.use() to a warning
 instead of an exception, for backwards compatibility - EF
2007年12月25日 Fix bug in errorbar, identified by Noriko Minakawa - EF
2007年12月25日 Changed masked array importing to work with the upcoming
 numpy 1.05 (now the maskedarray branch) as well as with
 earlier versions. - EF
2007年12月16日 rec2csv saves doubles without losing precision. Also, it
 does not close filehandles passed in open. - JDH,ADS
2007年12月13日 Moved rec2gtk to matplotlib.toolkits.gtktools and rec2excel
 to matplotlib.toolkits.exceltools - JDH
2007年12月12日 Support alpha-blended text in the Agg and Svg backends -
 MGD
2007年12月10日 Fix SVG text rendering bug. - MGD
2007年12月10日 Increase accuracy of circle and ellipse drawing by using an
 8-piece bezier approximation, rather than a 4-piece one.
 Fix PDF, SVG and Cairo backends so they can draw paths
 (meaning ellipses as well). - MGD
2007年12月07日 Issue a warning when drawing an image on a non-linear axis. - MGD
2007年12月06日 let widgets.Cursor initialize to the lower x and y bounds
 rather than 0,0, which can cause havoc for dates and other
 transforms - DSD
2007年12月06日 updated references to mpl data directories for py2exe - DSD
2007年12月06日 fixed a bug in rcsetup, see bug 1845057 - DSD
2007年12月05日 Fix how fonts are cached to avoid loading the same one
multiple times.
 (This was a regression since 0.90 caused by the refactoring of
 font_manager.py) - MGD
2007年12月05日 Support arbitrary rotation of usetex text in Agg backend. - MGD
2007年12月04日 Support '|' as a character in mathtext - MGD

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年11月27日 Released 0.91.1 at revision 4517
=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ=わ
2007年11月27日 Released 0.91.0 at revision 4478
2007年11月13日 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年11月13日 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年11月13日 Improved creation of default config files at build time for
 traited config package - DSD
2007年11月12日 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年11月12日 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年11月12日 Options to disable building backend extension modules moved
 from setup.py to setup.cfg - DSD
2007年11月09日 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年11月09日 Moved pyparsing back into matplotlib namespace. Don't use
 system pyparsing, API is too variable from one release
 to the next - DSD
2007年11月08日 Made pylab use straight numpy instead of oldnumeric
 by default - EF

 automatic level generation now works. - EF
2007年10月24日 Added ax kwarg to Figure.colorbar and pyplot.colorbar - EF
2007年10月19日 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年10月29日)
 - DSD
2007年10月15日 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年10月05日 remove generator expressions from texmanager and mpltraits.

 so I am enabling it. - JKS
2007年09月12日 Fixed a Axes.bar unit bug - JDH
2007年09月10日 Made skiprows=1 the default on csv2rec - JDH
2007年09月09日 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年09月08日 Eliminated gd and paint backends - EF
2007年09月06日 .bmp file format is now longer an alias for .raw
2007年09月07日 Added clip path support to pdf backend. - JKS
2007年09月06日 Fixed a bug in the embedding of Type 1 fonts in PDF.
 Now it doesn't crash Preview.app. - JKS
2007年09月06日 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年09月05日 Fixed Qt version reporting in setupext.py - DSD
2007年09月04日 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年09月03日 Added ability of errorbar show limits via caret or
 arrowhead ends on the bars; patch by Manual Metz. - EF
2007年09月03日 Created type1font.py, added features to AFM and FT2Font

 Xavier Gnata for the report and suggested fix - DSD
2007年08月13日 Use pickle to cache entire fontManager; change to using
 font_manager module-level function findfont wrapper for
 the fontManager.findfont method - EF
2007年08月11日 Numpification and cleanup of mlab.py and some examples - EF
2007年08月06日 Removed mathtext2
2007年07月31日 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年07月30日 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年07月29日 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年07月26日 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.

Hello everyone, I tried to install matplotlib but I am having some problems:
after installing all the necessary prerequisites (cairo, pycairo, pygo..., 
pygtk), I installed MATPLOTLIB as:
python setup.py build
python setup.py install
but when I finally try to use it by calling >>> from pylab import *
I receive the followinbg error:
Traceback (most recent call last):
 File "<stdin>", line 1, in ?
 File "/usr/local/cdat/lib/python2.4/site-packages/pylab.py", line 1, in ?
 from matplotlib.pylab import *
ImportError: No module named matplotlib.pylab
I hope anyone can help me,
thanks

Once when I found that NumPy released its version 1.0rc3,
I happily upgraded NumPy from 1.0rc1 to 1.0rc3 under WindowsXP.
A nightmare just happened. Matplotlib failed to run with NumPy 1.0rc3,
and I cannot found a NumPy 1.0rc1 on its download page.
Will matplotlib upgrade for NumPy 1.0rc3?
What can I do for this?
Grateful to any suggestion.
Thanks

This is the second bug fix release of the 0.83 series, but a couple of
new features have crept in.... The notes below include all new
features in 0.83; I've just been a little slow getting them typed up
:-)
You can read these with links at
http://matplotlib.sourceforge.net/whats_new.html
What's new in matplotlib 0.83
axis('scale')
 Added Mark Athen's 'scale' patch, so that on a scaled axis a circle
 looks like circle. See help(axis).
New cursor and span selector widgets
 Added new Cursor and HorizontalSpanSelector to
 matplotlib.widgets. See examples/widgets/cursor.py and
 examples/widgets/span_selector.py. Set useblit = True on gtkagg for
 significantly enhanced performance.
draw events
 You can use use matplotlib event handling to register a callback
 after figure draw using 'draw_event' which calls the callback with a
 DrawEvent instance
 def callback(event):
 #event.renderer is the backend Renderer instance
 pass
 connect('draw_event')
Full screen mode in GTK*
 Use 'f' to toggle full screen mode in the GTK backends. 
GTK and SVG fixes
 Steve Chaplin has made numerous updates to the GTK and SVG
 backends. See the CHANGELOG for details.
Reorganized config files
 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, and 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.
Using matplotlib.agg to draw paths
 Updated agg_test.py to demonstrate curved paths and fills.
CocoaAgg
 New CocoaAgg backend for native GUI on OSX, 10.3 and 10.4 compliant.
Qt enhancements
 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.
mathtext optimizations
 Upgraded pyparsing and applied Paul McGuire's suggestions for
 speeding things up. This more than doubles the speed of mathtext in
 my simple tests.

I created a wiki page on the scipy web site for people to upload tips,
tricks, HOWTOs and recipes for matplotlib. Everyone is encouraged to
contribute; you just need to get a login for the scipy page from
http://www.scipy.org/wikis/topical_software/join_form .
One easy way to contribute is to take a file from the examples
directory and explain and annotate it and place it on the wiki. You
can also upload images to show off your work. Beyond that, everything
is fair game: from a tutorial freezing mpl with py2exe to embedding
mpl in your favorite GUI to doing animations.
To get the ball rolling, I cleaned up my last post to the mailing list
and posted it with a screenshot

This fixes (we hope) the ipython run bug reported last week on the
mailing list.

Normally, this would have been a bugfix release, but I reorganized the
matplotlib configuration files so thought it best to tick the version
number. All of the configuration files and dirs (matplotlibrc,
tex.cache, ttffont.cache ) now reside in $HOME/.matplotlib (on windows
C:\Documents and Settings\youracct\.matplotlib). Please rename your
.matplotlibrc file to matplotlibrc and put it there.
Other change are 
2005年07月07日 Added Eric's MA set_xdata Line2D fix - JDH
2005年07月06日 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年07月05日 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年07月05日 Fixed default backend import problem when using API (SF bug
 # 1209354 - see API_CHANGES for more info - JDH
2005年07月04日 backend_gtk.py: require PyGTK version 2.0.0 or higher - SC
2005年06月30日 setupext.py: added numarray_inc_dirs for building against
 numarray when not installed in standard location - ADS
2005年06月27日 backend_svg.py: write figure width, height as int, not float.
 Update to fix some of the pychecker warnings - SC
 
2005年06月23日 Updated examples/agg_test.py to demonstrate curved paths
 and fills - JDH
2005年06月21日 Moved some texmanager and backend_agg tex caching to class
 level rather than instance level - JDH
