(Mike, i'm sorry for that i forgot to send my last response to matplotlib-users)
I meant the plot can't be constrained to x or y axis when I press 'x'
or 'y' key while operating on the pan mode. Panning plot just
relative to 'x' or 'y' axis is what i want.

Thanks for your example.
The pan mode works normally in the example, as many examples of
matplotlib package.
Yes, Only either panning/zooming or picking is enabled at one time.

Thanks for your detailed explanation. I'm sorry for my brief information.
My system is fedora 7. python version is 2.5, and matplotlib version
is 0.90.0.
I try to rebuild a small sample code, which is attached. Amazingly,
the pan mode is normal for this sample code. However, the problem
existing in my application code is still not yet identified.
What's the possible reasons? What kind of further information i should provide?
I'll keep exploration. Thank you for your guidance.
