Yusdi,
weblab looks like a really awesome project.
I haven't installed it yet, but I noticed that you released it LGPL.
Did you by chance already take into account this page?

Hi all,
I'm not sure if this is the right mailing list for this, so please bear with 
me if this is not for you.
I have developed a web front end for matplotlib, rather inspired by matlab 
development environment. You can find more of the details here:
http://www.physics.ox.ac.uk/users/santoso/Software.WebLab.html
It is usable right now although with some known problem especially in the 
area of secure code execution.
Any comments will be greatly appreciated.
Thanks and best regards,
Yusdi

Hi all,
anytime when requesting semilogy() on bar or hist chart, following error
occurs:
 File "/usr/lib/python2.5/site-packages/matplotlib-
0.90.0-py2.5-linux-i686.egg/matplotlib/backends/backend_qtagg.py", line 161,

0.90.0-py2.5-linux-i686.egg/matplotlib/backends/backend_agg.py", line 392,

 tverts = self.get_transform().seq_xy_tups(verts)
ValueError: Cannot take log of nonpositive value
I am sure that there is no negative value (just some zeros - this could be
the problem)
Anybody have an idea how to solve it?

Dear all,
some time ago (October last year) I mailed a patch for a bug in
backend_agg.py which is still not included. I attached the patch against
the latest SVN again.
The problem seems to be a missing parameter when calling the function
draw_ellipse.

Revision 3237 to fix set_ticklabels seems to have a problem: it breaks 
examples/mri_with_eeg.py.
