Hi,
I was wondering if you ever found a solution to this problem ?
I have the exact same issue with GTK (Agg or cairo) and WX backends
... I'm also under gentoo using ipython-0.10.1 and matplotlib-1.0.0
I don't have the warnings you have but same behavior, I have to call
show (if I don't a blank 'frozen' window is all that appears) but then
the ipython doesn't have control anymore.
Cheers,
 Sylvain

Can you post your eps file?
This may be related to the ps rasterizer you're using.
Regards,
-JJ

I don't think "polar" is a good fit for your case. Instead, you can
simply use "data" coordinate with explicit coordinate transformation.
Try something like;
 for i in xrange(5):
 theta = i*1.3+1.5
 xx = center[0]+(radius-4)*math.cos(theta)
 yy = center[1]+(radius-4)*math.sin(theta)
 pyplot.annotate(str(i+1), (xx, yy), color='g', va="center", ha="center")

Glad to hear that others find that code useful.
I just want to emphasize that this is not a general solution and never meant to.
Although I'm planning to include this functionality into the
axes_grid1 toolkit, I don't think this will be integrated with the
main matplolib.

Hi,
I am a new user of matplotlib so maybe my question is elementary, but 
have not been able to find an answer to my problem in the archive.
I would like to make a 2D plot of colored points of 3D data (clusters). 
My data looks like this:
11837.2120 -0.0858 2.0000
23975.2120 -0.0672 2.0000
37609.2120 -0.0306 2.0000
53263.9800 -0.0690 2.0000
72106.6760 0.2708 1.0000
92674.6760 -0.0129 3.0000
116758.676 -0.1245 3.0000
...
So I need to plot the first and second column as points on the x-y axis 
and color the points according to the numbers in the third column (which 
are integers ranging from 1 to5).
I'd appreciate any help. I realize something so typical should be 
somewhere in the documentation but I was not able to find it.
Thanks,
Paul
