It's unbeliable. Yes, it works now!!! At least.............. I had spend a lot of time with these!
So maybe is it a bug? Matplotlib developers: here you have a bug.


Thank you very much for your help, I coud never have thougt  that it was the problem.

Hello darkside,

I tried your example and it works for me (with mpl-svn) using GTKAgg and
doesn't work (like you reported) using TKAgg (Is this a bug?).
Maybe you can switch to GTKAgg?
Otherwise you should report the mpl-version you are using.
>-------------------------------------
import matplotlib
#matplotlib.use("TKAgg")
matplotlib.use("GTKAgg")
import pylab
>---------------------------------------

best regards,
Matthias
