[Matplotlib-users] Fixed patch relative to axes From: Thomas Robitaille - 2009-04-30 00:52:35 ```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 ```

 Re: [Matplotlib-users] Fixed patch relative to axes From: Thomas Robitaille - 2009-04-30 01:17:51 ```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?

(add_* could be modified to return the reference; maybe this would be worthwhile.)
