matplotlib.axes.Axes.set_picker

Axes.set_picker(self, picker)

Define the picking behavior of the artist.

Parameters:

Parameters:	`pickerNone or bool or callable` This can be one of the following: None: Picking is disabled for this artist (default). A boolean: If True then picking will be enabled and the artist will fire a pick event if the mouse event is over the artist. A function: If picker is callable, it is a user supplied function which determines whether the artist is hit by the mouse event: hit, props = picker(artist, mouseevent) to determine the hit test. if the mouse event is over the artist, return hit=True and props is a dictionary of properties you want added to the PickEvent attributes. deprecated: For `Line2D` only, picker can also be a float that sets the tolerance for checking whether an event occurred "on" the line; this is deprecated. Use `Line2D.set_pickradius` instead.
