[Matplotlib-users] Problems upgrading to mpl 0.87.4

[Joaquin A. M. <gat...@ho...>]

Dear all,
I upgraded matplotlib from 0.87.2.win32-py2.4 to 0.87.4. When trying to run 
the test program

#program text.py
import matplotlib as mpl
mpl.use('WXAgg')
mpl.interactive(False)
from pylab import plot, show
plot([1,2,3,4])
show()

double clicking on it or at the command line I got a warning from python.exe 
saying that library wxmsw26uh_vc.dll could not be found. This warning never 
appeared with vs 87.2.
Surprisingly, after saying OK to the warning the plot is plotted.
I searched the web and found that recently someone reported a similar 
problem with matplotlib 87.4 and this library to the enthon team. I searched 
my hard disk and I found this library in the support directory of 
wxGlade(!!!???). I put this library in the Python24 directory and the 
warning disappeared but then I got a new one:

C:\>python text.py

Traceback (most recent call last):
  File "text.py", line 6, in ?
    show()
  File "C:\Python24\Lib\site-packages\matplotlib\backends\backend_wx.py", 
line 1
193, in show
    figwin.canvas.draw()
  File "C:\Python24\Lib\site-packages\matplotlib\backends\backend_wxagg.py", 
lin
e 63, in draw
    self.bitmap = _convert_agg_to_wx_bitmap(self.get_renderer(), None)
MemoryError: _wxagg.convert_agg_to_wx_bitmap(): could not create the 
wx.Bitmap

I have the same problem with version 87.3. The problem only appears if I 
want to use WXAgg.
I went back to vs87.2 and everything works as expected.

Could someone help me?

Thanks
Joaquin
