classmatplotlib.axes.Axes.ArtistList(axes,prop_name,valid_types=None,invalid_types=None)#

A sublist of Axes children based on their type.

The type-specific children sublists were made immutable in Matplotlib3.7. In the future these artist lists may be replaced by tuples. Useas if this is a tuple already.

Parameters:

axesAxes: The Axes from which this sublist will pull the childrenArtists.
prop_namestr: The property name used to access this sublist from the Axes;used to generate deprecation warnings.
valid_typeslist of type, optional: A list of types that determine which children will be returnedby this sublist. If specified, then the Artists in the sublistmust be instances of any of these types. If unspecified, thenany type of Artist is valid (unless limited byinvalid_types.)
invalid_typestuple, optional: A list of types that determine which children willnot bereturned by this sublist. If specified, then Artists in thesublist will never be an instance of these types. Otherwise, notypes will be excluded.
