matplotlib.axes.Axes.set_contains

Axes.set_contains(self, picker)

Define a custom contains test for the artist.

The provided callable replaces the default contains method of the artist.

Parameters:

picker : callable

A custom picker function to evaluate if an event is within the artist. The function must have the signature:

def contains(artist: Artist, event: MouseEvent) -> bool, dict

that returns:

• a bool indicating if the event is within the artist
• a dict of additional information. The dict should at least return the same information as the default contains() implementation of the respective artist, but may provide additional information.
