Hi,
Is there an easy way to draw a patch or a patchcollection such that it always stays at the same relative position in a set of axes, rather than at the same pixel position? So for example, I would want to plot it at (0.1,0.1) relative to the axes, and if I zoom in I would still want it to stay at (0.1,0.1)
Thanks for any advice,
Thomas

With ipython -pylab:
ax = gca()
ax.fill([0.1, 0.2, 0.15], [0.1, 0.1, 0.15], transform=ax.transAxes)
draw()
then pan, zoom at will.

Thanks!
Is there an easy way to keep a reference to patches? I notice that for example
p = ax.add_patch(Circle((0.5,0.5),radius=0.5))
does not work (p is not a reference to the patch). Is there a way to keep a reference so I can update the properties of the patch at a later time?
Cheers,
Thomas

Split the command up:
p = Circle(...)
ax.add_patch(p, ...)
(add_* could be modified to return the reference; maybe this would be worthwhile.)
