Andre, my guess is that there's an attempt made to connect to the
(non-existant) X server. You can disable this by forcing a backend that
doesn't need the X server. Try
import matplotlib
matplotlib.use('Agg')
before the rest of your script.

Can you set verbose.level to debug-annoying in your

Also, if you have the development tools (XCode) installed on your mac,

You could try rebuilding matplotlib yourself. There are some OS-X
directions here:

This may mean, however, that it won't play nice with other parts of
scisoft. But this really is a matter of how and where scisoft was built

I have a displayed an image with imshow() under wxPython, and it looks great

Great. You may still want to let the scisoft guys know about this so
others won't hit up against it.

You can use \AA for angstrom (to conform to the (La)TeX standard).

Hi List,
I recently subjected some figures to an online 'quality analysis' done
by a journal I am submitting a paper to. The analysis stated that my

Can someone tell me if there is a way to rotate an axes instance?
I have,
figure(1)
ax1 = axes([0.0, 0.0, 1.0, 1.0], axisbg='0.95')
ax2 = axes([0.2, 0.1, 0.6, 0.8], axisbg='white')
and I would like to rotate ax2 30 degrees. It would look something like the

The toolbar is just a widget so you can do that the same way you show any
other widget in Qt. Something along the lines of:
- build a widget
- add a layout
- add the figure widget to the layout
- add the toolbar to the layout
- connect them

Hi,
When matplotlib uses an axis multiplier, as in x-axis in the script
below, the scale factor is not positioned properly on the figure as is
