running matplotlib or enthought.mayavi.mlab from a py-shell inside emacs on windows

问题

I can run the following code fine from a regular cmd shell:

import matplotlib.pyplot as plt
fig = plt.figure()
plt.show()

It launches a matplotlib window.
However, running inside emacs using shell or py-shell: the buffer just hangs and no window is launched. Anyone know what's going on here, or how to fix it ? Thanks.

got it working with ipython.el. had to add modify python26\scripts\ipython.bat

@"c:\Python26\python.exe" "-i" "c:\Python26\scripts\ipython.py" "-wthread" %*

then in emacs:

(setq ipython-command "c:/python26/scripts/ipython.bat")
(require 'ipython)
(py-shell)

Well after a tremendous amount of time and posting the bug on the matplotlib project page and the python-mode page I found out that supplying the arguments console --matplotlib in ipython.bat will do the trick with matplotlib 1.3.1 and ipython 1.2.0

This is what I have in my iphython.bat

@python.exe -i D:\devel\Python27\Scripts\ipython-script.py console --matplotlib %*
