[Matplotlib-users] Can't use WXAgg

[Barry D. <bl...@ad...>]

Having a problem with the WX backend; details follow.

I have wxPython 2.5 and matplotlib-0.60.2.win32-py2.3
installed.

My code snippet:
import matplotlib
matplotlib.use("WXAgg")
from matplotlib.matlab import *

Error msg:
Matplotlib backend_wx requires wxPython be installed

Code snippet from:
C:\Python23\Lib\site-packages\matplotlib\backends\backend_wx.py
try:
    from wxPython.wx import *
except:
    print >>sys.stderr, "Matplotlib backend_wx
requires wxPython be installed"
    sys.exit()    

I receive the following traceback when I try to invoke
this from the command line:

code snippet from:
C:\Python23\Lib\site-packages\wxPython\fonts.py
class wxFontPtr(wxObjectPtr):

This doesn't seem to be a problem specific to
matplotlib.  But, I'm wondering if anyone has
already solved this or I'm just missing something.

Thanks.
