[Matplotlib-users] unable to use matplotlib from inside emacs on windows

[Emin.shopper Martinian.s. <emi...@gm...>]

Whenever I try to use matplotlib from a python session inside emacs, python
freezes. What I do is start GNU Emacs version 21.1.3 for Windows, do ESC-x
shell and enter the commands shown below. Note that I set the backend to PS
and interactive to false, but my python interpreter still freezes. I suspect
that this is because matplotlib is generating some GUI events which upset
emacs. The example works fine if I run python through the shell without
emacs, but I would very much like to run python through an emacs session.
Similar problems happen with other backends. Any suggestions on how to solve
this problem would be much appreciated.

Thanks,
-Emin
