matplotlib-users Mailing List for matplotlib

This is just a heads up to those using the scipy backend for matplotlib, 
that CVS matplotlib contains the changes needed to coincide with the SVN 
version of scipy_core. This means that if you use CVS matplotlib, you 
will need a current version of scipy_core out of SVN to use scipy as a 
backend. The new scipy_core also has a scipy.base.mlab file to be 
completely backwards compatible (this simplifies the matplotlib.mlab 
file considerably).
A release of scipy_core with the new module structure for linear 
algebra, ffts, and random numbers will be made by the first of the year.

Hi all (particularly John),
I just compiled mpl on Linux Fedora core 4 with wxAGG support. In doing 
so, I got tripped up, for a little bit, with wx-config.
Once I figured it out, I ended up re-arranging the build_wxagg function 
a bit, just so that more meaning full error messages are likely.
The big difference is that even if WXAgg is on auto, you still get the 
message about wx-config. Here's my version of build_wxagg, and I've 
enclosed the whole file if you want to diff it. Perhaps you'd like to 
role these changes in.

 Well, it is there and it works. There is no toolbar, and the
save image button is not implemented. I really haven't had access to
a mac in a while, so there hasn't been much development. I basically
figured out the hard part of how to do the agg buffer to NSImage
bridge. The rest of the perks should be pretty simple. The code is
in backend_cocoaagg.py and the nib files are in the backends folder.
