matplotlib.artist.Artist.set_contains

Artist.set_contains(picker)[source]

Replace the contains test used by this artist. The new picker should be a callable function which determines whether the artist is hit by the mouse event:

hit, props = picker(artist, mouseevent)

If the mouse event is over the artist, return hit = True and props is a dictionary of properties you want returned with the contains test.

Parameters:
picker : callable
