Re: [Matplotlib-users] Bug in WXAgg on OS X and Matplotlib 0.87

Sam,

I wish I could be more help,. but maybe I can help steer your efforts  bit:

This sure looks like your error occurs when MPL is trying to convert 
from the wxagg internal image storage to a wxBitmap. As a test, I'd make 
sure the pure Agg back-end works fine (have it create a PNG). If so then 
font,s etc have nothing to do withyour trouble...it's all about the agg 
-> wx conversion. that's why I thought it could be caused by liniking to 
the wrong version of wx.

to make sure you have linked to the right version, you can use:

otool -L

on the wxagg libs that MPL builds. That should tell you which wx libs 
you've actuallylinked to.


With any luck, I'll have a chance to try to get this working on my 
system this week, and then maybe I'll be more help.

-Chris
