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.

Hi,
I'm using wxpython with matplotlib, I now have a figurecanvas embedded in my
program and I can plot stuff using:
a = self.fig.gca()
a.plot(x,y)
But what is the easiest and fastest way to draw a circle? I saw that the
artist class has a draw_arc function.. but I don't know how to use the

Hi Nicolas,
The attached script should illustrate one way to solve your problem.

Dear List,
How is it possible to write legend text with LateX fonts ?
Even with
rc('text', usetex=True)
the legend created with the command "legend" do not appear with LateX fonts.
I try something like :
pt.legend(('$\rm{total baryons}$'))
but the \rm is badly interpreted :-( .
Thanks for you

Hi,
I've been messing around with it alot now.. but I still can't get a colorbar
on my image plot..
I think i got close with this:
img is an image in a numpy.ndarray
a = self.fig.gca()# Get the current axes
a.imshow( img, cmap = cm.gray )
self.fig.colorbar(img)
But that gives me the erro

I'm not sure I understood well, but maybe you mixed something up and the

We need some more information.
Can you set "verbose.level" to "debug-annoying" in your
~/.matplotlib/matplotlibrc file?
Also, if you have the development tools (XCode) installed on your mac,
can you run python in gdb?

It's a bug in 0.91.2. This has been fixed on the maintenance branch (if
you're comfortable using SVN), or we do plan to release a bugfix 0.91.3
release soon.

It looks like matplotlib was built for a different version of iconv than
what you have on your machine. This may be a scisoft packaging problem,
you may want to bring this question to their attention. Perhaps the
version of OSX that scisoft was built on/for is different than what
you're runni
Is there anything I can do to update it by myself in the meanwhile?

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

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

Hi Mike,
I re-install the astronomy scisoft package and now the segmentation

You can pass an "interpolation" parameter to imshow, or set a default in
"image.interpolation" in your matplotlibrc. From the imshow docstring:
* interpolation is one of:
'nearest', 'bilinear', 'bicubic', 'spline16', 'spline36',
'hanning', 'hamming', 'hermite',
Thanks a lot for the help) I have noticed that \angstrom is not anymore
supported in 0.91.

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).

I recently subjected some figures to an online 'quality analysis' done

First I want to thanks for this amazing Matplotlib. It's fantastic!
My newbie question is how I can show the (zoom, pan, etc) toolbar in

I have noticed that in animation_blit_qt.py the toolbar is available, but it
seems to be done in a different way.

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
attached file.

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 tog

Hi,
When matplotlib uses an axis multiplier, as in x-axis in the script
