matplotlib-users Mailing List for matplotlib

George,
I am not a Windows user, so I can't report from my own experience, but 
here are some things to try:
1) Enthought Python suite: http://code.enthought.com/enthon/
The matplotlib version is slightly behind (0.87.3), but that may not 
matter for your present purposes.
2) Wait until a new matplotlib release compatible with current numpy is 
made. It has been under discussion, so I think it will be soon.
3) Until (2) occurs, use numarray or Numeric instead of numpy. They 
have been stable for a long time. I assume the Windows mpl compilation 
supports them.
4) Did you try 
http://prdownloads.sourceforge.net/numpy/numpy-0.9.8.win32-py2.4.exe?download
I think that is this the version that matches the Windows mpl 0.87.4, 
but if you really need scipy, then I think you would have to back up to 
an earlier version of that.

I am having running pylab from scipy in that I get the error messsage
 """ E:\ProgramFiles\Python\Lib\site-packages\matplotlib\_contour.py", line
17, in ?
 from matplotlib._ns_cntr import *
 RuntimeError: module compiled against version 90709 of C-API but this
version of numpy is 1000000"""
I am using the following modules
python 2.4 scipy-0.5.0
python 2.4 numpy-1.0b1
python 2.4 matplotlib-087.4
and running python windowsXp
I cant find other versions of matlinbplot, and when I try different
versions of numpy I get an error of the sort that
it cant load oldnumeric.
Can someone suggest a solution to my problem
thanks

On some backends, eg qt, we can do the blit via python method calls
and python buffer objects. I know this can be done w/ pygtk and it
has been on my wishlist to remove the gtk extension code and use pure
python since getting rid of gtk, wx and tk devel headers and libs at
build time would significantly reduce the kinds of cross-platform
build and runtime issues we are seeing from this GUI dependent
extension code.
Charlie, since you are pretty familiar with the blitting API, perhaps
you could take a look and see how much work it would be to do wx
blitting w/o extension code. I'd be happy to add some additional
helper methods in agg if need be, as we did for qt. I'd be willing to
trade a little performance to avoid these distribution headaches.

Matplotlib didn't used to link against the wxpython c-api. The recent
versions are linked against the unicode version of wx, not the ansi.
You can install the unicode version. We are trying to decide how to
handle this.

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

Hi,
Try editing your matplotlib rc file and change these font preferences
 font.serif : New Century Schoolbook, Century Schoolbook L,=20
Utopia, ITC Bookman, Bookman, Bitstream Vera Serif, Nimbus Roman No9 L,=20
Times New Roman, Times, Palatino, Charter, serif
 font.sans-serif : Lucida Grande, Verdana, Geneva, Lucida,=20
Bitstream Vera Sans, Arial, Helvetica, Avant Garde, sans-serif
 font.cursive : Apple Chancery, Textile, Zapf Chancery, Sand,=20
cursive
 font.fantasy : Comic Sans MS, Chicago, Charcoal, Impact,=20
Western, fantasy
 font.monospace : Andale Mono, Bitstream Vera Sans Mono, Nimbus=20
Mono L, Courier New, Courier, Fixed, Terminal, monospace
by moving the bitstream fonts to the front
Next, you have to use LaTeX for all your text in your plot.
So, use:
rc('text', usetex=3DTrue)
xlabel(r'\texrtbf{toto}')
Best regards.
