trying to use latex

Hi group,

I wanted to try to usetex for my matplotlib plots, and thought that I
had everything neccessary installed, but it doesn`t work. Perhaps
someone in the group have some idea what is wrong here? Im using
MikTex on xp and have the dvipng-miktex pakage installed. thx

334, in draw
    bbox, info = self._get_layout(renderer)
  File "C:\\Python23\\lib\\site-packages\\matplotlib\\text.py", line
179, in _get_layout
    w,h = renderer.get_text_width_height(
  File "C:\\Python23\\lib\\site-packages\\matplotlib\\backends\\backend_agg.py",
line 237, in get_text_width_height
    Z = self.texmanager.get_rgba(s, size, dpi, rgb)
  File "C:\\Python23\\lib\\site-packages\\matplotlib\\texmanager.py",
line 276, in get_rgba
    pngfile = self.make_png(tex, dpi, force=False)
  File "C:\\Python23\\lib\\site-packages\\matplotlib\\texmanager.py",
line 113, in make_png
    dvifile = self.make_dvi(tex)
  File "C:\\Python23\\lib\\site-packages\\matplotlib\\texmanager.py",
line 105, in make_dvi
    shutil.move(dvitmp, dvifile)
  File "C:\\Python23\\lib\\shutil.py", line 174, in move
    copy2(src,dst)
  File "C:\\Python23\\lib\\shutil.py", line 83, in copy2
    copyfile(src, dst)
  File "C:\\Python23\\lib\\shutil.py", line 38, in copyfile
    fsrc = open(src, 'rb')

Have you read the wiki? http://www.scipy.org/Wiki/Cookbook/Matplotlib/UsingTex

An intermediate dvi file is missing, probably because the latex executable is
not on your path.

After upgrading from MPL 0.82 to 0.87 and tried again, the message
from MPL was that I needed tex version 0.31415 or later. I have
0.3141592 and the reason why MPL didn`t find it is described in bugs
on Sourceforge with the title
"Bug with text.usetex = true on WinXP with MiKTeX". So I just edited
__init__.py and latex now seems to work with MPL.
