[matplotlib-devel] Updated (URLs) matplotlibrc files

[Sandro Tosi]

Hello,
I've updated lib/matplotlib/mpl-data/matplotlibrc to use new URLs on
matplotlib.sf.net (there's just one I'm not sure marked with '(** NOT
SURE**)').

Sadly, that file is not under SVN so I don't have a "svn diff" to
propose, but the whole updated file, here attached; if it might be
easier, here is the sed cli I used (all on a single line):

sed 
's|http://matplotlib.sourceforge.net/interactive.html|http://matplotlib.sourceforge.net/users/shell.html
\(\*\*NOT SURE\*\*\)|;
s|http://matplotlib.sourceforge.net/matplotlib.lines.html|http://matplotlib.sourceforge.net/api/artist_api.html\#module-matplotlib.lines|;
s|http://matplotlib.sourceforge.net/matplotlib.patches.html|http://matplotlib.sourceforge.net/api/artist_api.html\#module-matplotlib.patches|;

lib/matplotlib/mpl-data/matplotlibrc

Please consider add this to the upcoming .3 release.

Re: [matplotlib-devel] Updated (URLs) matplotlibrc files

[Michael Droettboom]

Thanks for the patch.  I've committed this to the branch and trunk so it 
should make it into the next bugfix release.

For future reference, lib/matplotlib/mpl-data/matplotlibrc is built from 
matplotlibrc.template which is under version control, so you can always 
just send an svn diff against that if you find further errors.

Cheers,
Mike

 There is no  or the type is not defined in stdint.h?

 Maybe as a workaround you could use mingw...

Thanks for the report.  I'll make the change in SVN.

 I meant that uint8_t is not a standardized C++ type.  If that's the case,
 wouldn't it be better to tweak the code to use something standard rather
 than just use a compiler that supports the non-standard type?  Especially
 given that the official Python 2.5 build uses this compiler?

[matplotlib-devel] Status of Wx backend

[Ryan May]

Hi,

What's the official status of the plain Wx backend (not WxAgg) ? I'm
noticing that the following script produces black outlines with Wx, but
should not (and does not on other backends).  I also noticed font
differences between the two.  I was curious if this is something to track
down or if plain Wx is just kind of abandoned.  I've also attached images
made with Wx and GtkAgg.

#!/usr/bin/env python
import matplotlib.mlab as mlab
from pylab import figure, show
import numpy as np

x = np.arange(0.0, 2, 0.01)
y1 = np.sin(2*np.pi*x)
y2 = 1.2*np.sin(4*np.pi*x)

# now fill between y1 and y2 where a logical condition is met.  Note
# this is different than calling
#   fill_between(x[where], y1[where],y2[where]
# because of edge effects over multiple contiguous regions.
fig = figure()
ax = fig.add_subplot(111)
#ax.plot(x, y1, x, y2, color='black')
ax.fill_between(x, y1, y2, where=y2>y1, facecolor='#8388FC',
edgecolor='None')
ax.fill_between(x, y1, y2, where=y2<=y1, facecolor='#C14F53',
edgecolor='None')
ax.set_title('fill between where')

show()

Thoughts?

Committed to the trunk in r6899... Thanks!

And, sheesh, SourceForge's SVN server is slooow today for me, although
it seems to have finally improved.
