That sounds fine to me. I just wanted to make sure that I wasn't glossing over a bug that could turn up elsewhere. Thanks, Darren On Monday 10 March 2008 08:46:36 am Michael Droettboom wrote: > No, I didn't see this message, but I think we arrived at the same > conclusion. I think the solution

No, I didn't see this message, but I think we arrived at the same conclusion. I think the solution is just to calculate the width and height in the same way in both places (copy_to_bbox and the Qt blitting code in Python). We can't change bbox.bounds, since many other parts of the code rely o

Sorry, I didn't see this latest e-mail before I replied before. I see the shearing now that I've adjusted window size. Maybe it could be related to the fact that width != span? Anyway, I'll investigated further and get back. Cheers, Mike Darren Dale wrote: > On Friday 07 March 2008 4:58:03

I am having some trouble with the Cursor widget with the qt4agg backend. Here is a short script which works with the gtkagg backend with useblit either true or false: -- from matplotlib import rcParams rcParams['backend']='gtkagg' from pylab import * from matplotlib.widgets import Cursor
