Méthode matplotlib.artist.Artist.set_picker

Signature de la méthode set_picker

def set_picker(self, picker) 

Description

help(Artist.set_picker)

Define the picking behavior of the artist.

Parameters
----------
picker : None or bool or float 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 float: If picker is a number it is interpreted as an
      epsilon tolerance in points and the artist will fire
      off an event if its data is within epsilon of the mouse
      event.  For some artists like lines and patch collections,
      the artist may provide additional data to the pick event
      that is generated, e.g., the indices of the data within
      epsilon of the pick event

    - 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.
