Classe « Artist »

Méthode matplotlib.figure.Artist.get_cursor_data

Signature de la méthode get_cursor_data

def get_cursor_data(self, event) 

Description

help(Artist.get_cursor_data)

Return the cursor data for a given event.

.. note::
    This method is intended to be overridden by artist subclasses.
    As an end-user of Matplotlib you will most likely not call this
    method yourself.

Cursor data can be used by Artists to provide additional context
information for a given event. The default implementation just returns
*None*.

Subclasses can override the method and return arbitrary data. However,
when doing so, they must ensure that `.format_cursor_data` can convert
the data to a string representation.

The only current use case is displaying the z-value of an `.AxesImage`
in the status bar of a plot window, while moving the mouse.

Parameters
----------
event : `~matplotlib.backend_bases.MouseEvent`
