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:
Enthought Edition build 1057

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.

Update to my previous post:
When I use the command line to use WXAgg, I receive
the following traceback:
>>> import matplotlib
>>> matplotlib.use("WXAgg")
>>> from matplotlib.matlab import *
Traceback (most recent call last):
File "<stdin>", line 1, in ?
File
"C:\Python23\Lib\site-packages\matplotlib\matlab.py",
line 144, in ?
from backends import new_figure_manager,
error_msg, \

File
"C:\Python23\Lib\site-packages\matplotlib\backends\backend_wxagg.py",
line 20, in ?
from backend_wx import FigureManager
File
"C:\Python23\Lib\site-packages\matplotlib\backends\backend_wx.py",
line 116, in ?
wxapp = wxPySimpleApp()
NameError: name 'wxPySimpleApp' is not defined
This means that it gets past the try-except in
backend_wx.py, but can't find wxPySimpleApp.
In the previous post, when runing the code from a
file, the exception was caught and
a sysexit() occurred.
I don't understand why in one case the exception is
caught and not in the other.
In either case, I'm still unable to use the wx
backend.
Thanks.

Are you using the standard python shell or an IDE like pycrust? If
the latter, it may be overriding the sys,exit which is why you aren't
seeing it. From your previous post, it looks like your wx
installation is in bad shape. Until you can do 'from wxPython.wx
import *' from the standard python shell, I wouldn't bother with
trying to tweak matplotlib.
I didn't see any error message like the one you were getting in the
wxpython archives - you might try the wx mailing list.

John, I'm using a windows XP shell; so no extra stuff running. I did run all of the wxPython 2.5 demos before trying my old matplotlib code. The wxPython demos ran fine. My "old" matplotlib code ran under matplotlib 0.54.2 with wxPython 2.4.1.2; I tested all of the backends with success. After upgrading to wxPython 2.5 all of my matplotlib code is broken. I even upgraded to the latest matplotlib, 0.61. Still doesn't work. I'll try a clean reinstall next. If that doesn't work I'll go to the wx lists. Thanks.

John, Clean install worked. Must have had some version leftovers around. Thanks.
