matplotlib-0.90.1 has just been released. matplotlib is a graphing
package for python which can be used interactively from the python
shell ala Mathematica or Matlab, embedded in a GUI application, or
used in batch mode to generate graphical hardcopy, eg in a web
application server. Many raster and vector outputs are supported
(PNG, SVG, PDF, PS, and more). You can get the source release, eggs
and binary builds for OS X and windows at the download link below

==============================================================
2007-06-02 Released 0.90.1 at revision 3352
2007-06-02 Display only meaningful labels when calling legend()
without args. - NN
2007-06-02 Have errorbar follow the color cycle even if line is not
plotted.
Suppress plotting of errorbar caps for capsize=0. - NN
2007-06-02 Set markers to same alpha value as line. - NN
2007-06-02 Fix mathtext position in svg backend. - NN
2007-06-01 Deprecate Numeric and numarray for use as numerix. Props to
Travis -- job well done. - ADS
2007-05-18 Added LaTeX unicode support. Enable with the
'text.latex.unicode' rcParam. This requires the ucs and
inputenc LaTeX packages. - ADS
2007-04-23 Fixed some problems with polar -- added general polygon
clipping to clip the lines a nd grids to the polar axes.
Added support for set_rmax to easily change the maximum
radial grid. Added support for polar legend - JDH
2007-04-16 Added Figure.autofmt_xdate to handle adjusting the bottom
and rotating the tick labels for date plots when the ticks
often overlap - JDH
2007-04-09 Beginnings of usetex support for pdf backend. -JKS
2007-04-07 Fixed legend/LineCollection bug. 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
