[matplotlib-devel] Problem with pan/ZOOM on semilog plot

[David T. <dav...@gm...>]

Hi,

 I've just discover a problem with the pan/zoom tool.
When using the pan/zoom tool (in the toolbar) on a semilogy plot the
zoom does not work correctly.
To visualize the problem launch the small script in attachment press the
pan/zoom button and use the zoom on the x axis direction -> you will see
the button part of the curve directly jumping at the bottom of the graph
  whereas you would expected it not to move...
I evidence this problem using GTKAgg but also with the OSX backend (did
not try other backend).
Matplotlib version is the latest svn on a MacOS X platform.

Thanks in advance,

David
