Dear all,
I have been using the WXAgg backend with matplotlib and have been
coming across an occasional error. Unfortunately, it is a little
difficult to trap as it doesn't happen every time! Running on Windows
with python 2.5.2, matplotlib 0.98.0 (installed from the binary) and
wx version
Are you using the wxAgg backend or just wx? Which version of matplotlib?
If you're using 0.98.x with the wx backend, things are *very* slow. The
performance of wx.GraphicsContext (that is uses under the hood) is
terrible. You may want to try switching to the WxAgg backend, which,

Quoting Fabrice Silva:
Using version 0.91.2, I do not manage to push ticks labels to
the right side of the axis, keeping ticks lines on both
sides. How can I do it ?
One solution is
yax = gca().yaxis
yax.set_ticks_position('right')
# labels right side; removes left ticks
There seems to have been a change to the behavior of the 'alpha' keyword option
to scatter(): where previously alpha only affected the facecolor, and the
edgecolor always had an alpha of 1.0, alpha now seems to affect both facecolor
and edgecolor. Tested with 0.93.1 and 0.98. Tested with new

For what it's worth, apparently you can speed up GraphicsContext code
substantially if you use it right -- i.e.

Can you be more specific about this
no. I haven't done much with it myself.

As a quick-fix workaround, you can do:
from matplotlib.pyplot import *
p = scatter([0,1,2,3], [4,5,6,7], c ='k', alpha=0, edgecolor = 'k')
p._alpha = 1.0
p.set_edgecolor('k')
show()
But the deeper question is for the rest of the list is... what's the
correct behavior? Should we just revert to

sorry :-(
It also is different from what I was talking about in the sense of
clipping. The effect I see is that when an explicit clipping rectangle
is applied (e.g. the axes), speed

Hi everyone,
The code below was working for me as a charm, but since the new matlplotlib
flavor 0.98, I'm getting this error message:
AttributeError: 'CirclePolygon' object has no attribute 'get_verts'
Any idea?

I realize this is way outdated now, but I came across the same
problem. My imshow command would display fine in the
xwindow and all plotting devices except for .ps. Taking the advice
you guys gave, I tracked it down
to pdftops in the backends.ps.py file. I changed the command from:

There was recently a post on Radar/Spider plotting
(http://sourceforge.net/mailarchive/message.php?msg_id=4845303A.9050204%40epcc.ed.ac.uk).
I too am interested in creating Radar plots with matplot. Is there a
simple way to do this?
Thanks,
Curtis
