[Matplotlib-users] Axes changing position while programmatically zooming in/out

[Andrea G. <and...@gm...>]

Hello list,

    I am creating a series of plots automatically. During the first 10 of
them, I gradually zoom in to a specific area, while during the last 10 I
zoom out to the original axes limits.

The problem is, I am only changing the x/y limits of the axes, not their
position. However, when savefig is called on the figure, the actual axes
position changes (even thought I specifically give the axes position myself
at every iteration).

I am attaching a sample application which demonstrates the problem. This is
on Windows 7, Python 2.7.3, WXAgg, Matplotlib 1.2.0. The output I get for
the axes bbox is as follow (from the attached script):

Does anyone see what I may be doing wrong?

Thank you in advance for your help.
