matplotlib-users Mailing List for matplotlib

Eric,
This works great and fixes all the issues I saw. Thanks much. I didn't
see the anomaly you mentioned.
PS My ISP (dreamhost.com)'s email server is SpamCop's blackhole, which
means SourceForge will reject it from the mailing list unless they've
resolved the issue already.

Andrew,
I have committed another revision of the aspect-ratio handling. It seems to work pretty well, and I think pan/zoom work in a reasonable fashion now. Many times in the past, however, I have thought that aspect-ratio handling was working adequately, and every time someone has found a major bug. This time is probably no exception.
There can be some anomalies when the window is resized quickly--that is, grabbing a window corner and slinging it around with axis('equal') can cause some incorrect choices of the view limits. I haven't figured out why. Although I certainly would like to understand and fix it, it is not a top priority at the moment because I don't think it is a major problem in practice.

Hum,
I did, but it is still pretty rough. I did some changes to it a while ago t=
o
use objects and it still isn't complete.
I'll try to get the class in working order by the weekend.

The 0.87.2 release requires numpy-0.9.6.

Hi,
=20
 I'm using Python 2.4.1, numpy-0.9.8, and matplotlib-0.87.2 on a
Windows XP computer.
 Problem is that any attempt to import pylab results in a crash.
 Using "python -v", the culprit seems to be the following line:
=20
 # c:\Python24\lib\site-packages\matplotlib\_transforms.pyc matches
c:\Python24\lib\site-packages\matplotlib\_transforms.py
 import matplotlib._transforms # precompiled from
c:\Python24\lib\site-packages\matplotlib\_transforms.pyc
 Any ideas and solutions to this issue?
