Méthode matplotlib.figure.Figure.ginput

Signature de la méthode ginput

def ginput(self, n=1, timeout=30, show_clicks=True, mouse_add=<MouseButton.LEFT: 1>, mouse_pop=<MouseButton.RIGHT: 3>, mouse_stop=<MouseButton.MIDDLE: 2>) 

Description

help(Figure.ginput)

Blocking call to interact with a figure.

Wait until the user clicks *n* times on the figure, and return the
coordinates of each click in a list.

There are three possible interactions:

- Add a point.
- Remove the most recently added point.
- Stop the interaction and return the points added so far.

The actions are assigned to mouse buttons via the arguments
*mouse_add*, *mouse_pop* and *mouse_stop*.

Parameters
----------
n : int, default: 1
    Number of mouse clicks to accumulate. If negative, accumulate
    clicks until the input is terminated manually.
timeout : float, default: 30 seconds
    Number of seconds to wait before timing out. If zero or negative
    will never time out.
show_clicks : bool, default: True
    If True, show a red cross at the location of each click.
mouse_add : `.MouseButton` or None, default: `.MouseButton.LEFT`
    Mouse button used to add points.
mouse_pop : `.MouseButton` or None, default: `.MouseButton.RIGHT`
    Mouse button used to remove the most recently added point.
mouse_stop : `.MouseButton` or None, default: `.MouseButton.MIDDLE`
    Mouse button used to stop input.

Returns
-------
list of tuples
    A list of the clicked (x, y) coordinates.

Notes
-----
The keyboard can also be used to select points in case your mouse
does not have one or more of the buttons.  The delete and backspace
keys act like right-clicking (i.e., remove last point), the enter key
terminates input and any other key (not already used by the window
manager) selects a point.
