Sounds like you have a problem with the permissions on your home
directory. Can you create the directory ~/.matplotlib yourself and make
it writable by yourself? The commands to do that would be something like
mkdir ~/.matplotlib
chmod u+w ~/.matplotlib

Thanx all,
Can it be used to do a projection not only on the xoy axis but also on the
xoz and yoz?

Hi everybody,
Could you help me with this problem: I can import matplotlib from the 
shell, it displayed this
 >>> import matplotlib
Traceback (most recent call last):
 File "<stdin>", line 1, in <module>
 File "/usr/lib/python2.6/dist-packages/matplotlib/__init__.py", line

 fname = matplotlib_fname()

 fname = os.path.join(get_configdir(), 'matplotlibrc')

I don't know what to do.
Best regards

Try calling subplots_adjust(right=0.99) before calling colorbar. Then 
the colorbar axes will be generated by stealing space from the enlarged 
main axes.
