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.
