Pan/Zoom with Matplotlib

[Czenek]

Hi,
can I use somehow standard matplotlib's functions pan/zoom? I would
like to zoom my created graph after double-clicking and move with it
after keyboard (arrow) pressing (similar as Google Maps). And I want
also to control how much it zooms and how far is the graph moved after
pressing a key (or double-clicking).
So are there any appropriate API functions which can be connected with
keyboard and mouse events?

Thanks
Czenek

PS: I'd like to use it with tk.

And

import matplotlib as mpl
f=mpl.figure(fi gsize(5,5),dpi= 100)
sbplt=f.add_sub plot(111)

....

while 1:
x1,x2=sbplt.get _xlim()
y1,y2=sbplt.get _ylim()
sbplt.set_xlim( x1+0.1,x2+0.1)
sbplt.set_ylim( y1+0.1,y2+0.1)
f.canvas.draw()


this works pretty well on Linux, but the movement on Windows is slow
and therefore it is not smooth.

Any advice for better smoothness?
