matplotlib-devel Mailing List for matplotlib

Hi all,
I'm having trouble getting an MPL 0.90.0 working with wxPython 2.8 on OS-X.
Does anyone know what the egg on the sourceforge site is built with?
Is that documented somewhere?
As I understand it, Ken made some changes for wxPython 2.8 in svn, but I 
don't see any mention of them in the 0.90.0 CHANGELOG, so it looks like 
they haven't made it into the distribution yet. darn.
oh well, off to set things up to compile.
-Chris

Well I've got a bit of work to do which involves 3D stuff in the
coming week or so, so if I run up against anything else I'll keep the
patches coming. Thanks for the quick commit.
Cheers,
Tim

Thanks Tim, I just committed this. I see that my sinister plan of
releasing the 3d stuff w/o support in hopes of reeling in contributers
is starting to work....
<laughs maniacally>

Hi All,
I've attached a patch which addresses two small issues. The first is a
bug in patches.py. When doing 3d scatter plots
xs, ys = zip(*self.xy) (line 480)
crashes, as the right hand side expands to 3 values.
The other is a speedup, normalising an entire array at once, rather
than element by element, speeding up the attached script by a factor
of 6x (and upgrading my actual application from 'too slow' to 'quite
reasonable' :-)
Cheers,
Tim

This looks like a great start, Jouni. At least three times in the past, I h=
ave=20
tried to get started on writing a dvi parser for exactly this purpose, and =
I=20
never could make any real progress on it in the amount of time I had=20
available. Plus, I was in over my head and had to relearn a lot each time I=
=20
started over. I'm really impressed with what you have done. Nice work!

I just committed the beginnings of draw_tex for the pdf backend, which
uses the dvi reader in the new file dviread.py. This is all in a very
rudimentary stage, but I'm committing now since I won't likely have
much time to work on this in the near future. In the meantime, if
anyone's interested in developing it further, take a look at
backend_pdf.py for caveats and how to enable it.
The following script produces the attached output; note that the
\alpha is broken (must be some encoding issues) but the underscore
command \_ works, unlike in plain mathtext.
#!/usr/bin/env python
import matplotlib
matplotlib.use('PDF')
from pylab import *
rc('text', usetex=True)
rc('font', serif='Computer Modern Roman', size=10)
subplot(111)
setp(gca(), xticks=[], yticks=[])
text(0.5, 0.5, r'$f(x)=\alpha\_1$', fontsize=10)
savefig('foobar.pdf')
