Event handling

Hi all,

Is it possible to restrict the mouse movements to the points of a graph (curve tracking) ?

So far I am able to obtain the location of the mouse in data coordinates if the mouse is over an axes.

A code snippet is attached.

Thanks in advance.

No, but you can obtain the vertices of the line that are within a
tolerance of the clicked point using the picking functions. See the
tutorial at

  http://matplotlib.sourceforge.net/users/event_handling.html

and the "pick*" demos at

  http://matplotlib.sourceforge.net/examples/event_handling/index.html
