zooming problem on figures with shared axes #2790
Description
Hi!
I am trying to use axes shared across different figures and run into a funny effect when I resize one of the windows.
If I do:
import pylab as p
a0 = p.subplot(121)
p.imshow(p.rand(100,100))
a1 = p.subplot(122,sharex=a0,sharey=a0)
p.imshow(p.rand(100,100)**2)
p.figure()
a2 = p.subplot(121,sharex=a0,sharey=a0)
p.imshow(p.rand(100,100)**3)
zooming into one of the axes does as expected: the other two follow.
However, when I resize one of the windows, all three axes zoom out completely (and not in one jump, it looks like seeing the image would be slowly falling away...)
Interestingly if I close the figures my shell still keeps on doing stuff backstage: my cpu is 100% busy. I tried this both under Ipython and a normal python shell.
Under Ipython a ctrl-C leads to the following traceback.
Original exception was:
Traceback (most recent call last):
