[Matplotlib-users] Error when zooming manually with the mouse outside of the axes

[Eric O L. (EOL) <Eri...@no...>]

With the Mac OS X backend (at least…), error messages are repeatedly printed
when the mouse leaves the axes rectangle:


Traceback (most recent call last):

TypeError: integer argument expected, got float

This problem is annoying because the error messages clutter the terminal,
and useful printed information leaves the screen. :)

Configuration: Mac OS X 10.7, latest MacPort's Python and modules,
Matplotlib 1.0.1 with Mac OS X backend.
