Dear matplotlibbers,
I am currently trying to convince matplotlib using LaTeX for text
processing. Unfortunately, it seems to hang up at some point in the
minimal example script from the user's guide (also posted below)
without throwing any warning or error. As I am new to python and
matplotlib, I am not able to track down the problem.
My OS is Windows 7 (Professional), 64bit, using MikTeX and GPL
Ghostscript (all in my PATH), following is an example cmd.exe session:
C:\somewhere>python --version
Python 2.6.4
c:\somewhere> tex --version && latex --version && pdftex --version &&
pdflatex --version

(Here it hangs up AFAIK doing nothing, at least python is not using
CPU resources)
The --verbose-debug flag only shows the modules loaded in addition to
the latter output, but at the point of hangup no additionally
information is provided.
I am very thankful for any hint in which direction to look,
Best regards,
