2006年05月27日 Committed a patch to prevent stroking zero-width lines in
 the svg backend - DSD
2006年05月24日 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年05月23日 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

 offset text when the ScalarFormatter is used; FixedFormatter
 augmented to accept and display offset text. - EF

 figure.py and pylab.py.
 Fixed aspect-handling bug reported by Michael Mossey.

 texmanager imports. Now these imports only occur if text.usetex
 rc setting is true - DSD
2006年04月10日 Committed changes required for building mpl on win32
 platforms with visual studio. This allows wxpython
 blitting for fast animations. - CM

And just to prove that ipython is wedded to mpl til death do us part:
http://scipy.net/pipermail/ipython-user/2006-June/001750.html
We put 0.7.2 of ipython out also yesterday, and it does include a
number of fixes to the threading support that pylab requires with the
WX, GTK or Qt backends.
Cheers,

ps - it seems the matplotlibrc file at:
http://matplotlib.sf.net/matplotlibrc
is a bit outdated:
In [1]: import matplotlib
/home/fperez/tmp/local/lib/python2.3/site-packages/matplotlib/__init__.py:947:
UserWarning: Bad val "free" on line #204
 "image.aspect : free # free | preserve"
 in file "/home/fperez/.matplotlib/matplotlibrc"
 not a valid aspect specification
The one in the source distro is fine (I'm in the middle of updating,
so I noticed).

mathtext doesn't currently support frac (but hopefully it will by the
end of the summer as we have a google summer-of-code student working
on mathtext). As Ryan noted, if you have access to TeX/LaTeX on your
system, you can use that to render your equations
Requirements:
 tex
 *Agg backends: dvipng
 PS backend: latex w/ psfrag, dvips, and Ghostscript 8.51
 (older versions do not work properly)

You can set matplotlib up to use LaTeX, but it can be a little bit of
work to get it going. The results are quite beautiful though.
set usetex = 1 in yout matplotlibrc file to try it out. It depends on
LaTeX, dvipng, and ghostscript.

Does anyone know the syntax for fraction used in mathtext? The LaTex
version is \frac{num}{denom} but this gives an error.
Thanks

The script examples/backend_driver.py does just this -- it runs a
most of the examples and generates output in a variety of formats
(PNG, PS, SVG). I usually tun this before releases and load all the
images into a viewer to check for bugs. We could add these generated
images to a web page...., but sourceforge is already complaining that
I am over my quota. Apparently, I can ask for more space, though.

I have always felt that it would be useful to have available a 
collection of plots corresponding to the code in the examples file as 
part of the distribution. (for those examples that generate plots, of 
course)
The plot names would be the same as the example code that generated 
them. It could be in an economical format (png?) so as to not take up a 
lot of space.
For my own part, I tend to be lazy and would like a way to peruse the 
new capabilities before I decide to install the new release or wait 
for the next.
This would also provide a complete gallery to help those considering 
adoption.
It would also provide a verification for persons testing a new install 
that this is what the results of running the examples should be.
just an idea.

Hi,
I am using a second y axis on the right with twinx() like the
following:
ax =3D subplot(111)
plot_date(..., label=3D'foo')
ax.xaxis.set_major_locator(month3)
ax.xaxis.set_major_formatter(DateFormatter('%Y-%m'))
ax.xaxis.set_minor_locator(month1)
ax.autoscale_view()
labels =3D ax.get_xticklabels()
setp(labels, rotation=3D60)
ax2 =3D twinx()
plot_date(..., label=3D'bar')
[...]
I am then repeating the xaxis.set_* functions for ax2 so that they
overprint the ax ones, otherwise I get two differently formatted x
axes. I would however just like to use the first xaxis setting and
not print it for ax2 at all - how could I do that?
Also, I can't find how to merge the two labels 'foo' and 'bar' into
a single legend, is there way to do that?
TIA,
 Colin
