matplotlib.pyplot.figure#

matplotlib.pyplot.figure(num=None, figsize=None, dpi=None, *, facecolor=None, edgecolor=None, frameon=True, FigureClass=<class 'matplotlib.figure.Figure'>, clear=False, **kwargs)[source]#

Create a new figure, or activate an existing figure.

Parameters:
numint or str or Figure or SubFigure, optional

A unique identifier for the figure.

If a figure with that identifier already exists, this figure is made active and returned. An integer refers to the Figure.number attribute, a string refers to the figure label.

If there is no figure with the identifier or num is not given, a new figure is created, made active and returned. If num is an int, it will be used for the Figure.number attribute, otherwise, an auto-generated integer value is used (starting at 1 and incremented for each new figure). If num is a string, the figure label and the window title is set to this value. If num is a SubFigure, its parent Figure is activated.

figsize(float, float), default: rcParams["figure.figsize"] (default: [6.4, 4.8])

Width, height in inches.

dpifloat, default: rcParams["figure.dpi"] (default: 100.0)

The resolution of the figure in dots-per-inch.

facecolorcolor, default: rcParams["figure.facecolor"] (default: 'white')

The background color.

edgecolorcolor, default: rcParams["figure.edgecolor"] (default: 'white')

The border color.

frameonbool, default: True

If False, suppress drawing the figure frame.

FigureClasssubclass of Figure

If set, an instance of this subclass will be created, rather than a plain Figure.

clearbool, default: False

If True and the figure already exists, then it is cleared.

layout{'constrained', 'tight', LayoutEngine, None}, default: None

The layout mechanism for positioning of plot elements to avoid overlapping Axes decorations (labels, ticks, etc). Note that layout managers can measurably slow down figure display. Defaults to None (but see the documentation of the Figure constructor regarding the interaction with rcParams).

**kwargs

Additional keyword arguments are passed to the Figure constructor.

Returns:
Figure

Notes

Newly created figures will be passed to the new_figure_manager function provided by the current backend, which will install a canvas and a manager on the figure.

If you are creating many figures, make sure you explicitly call pyplot.close on the figures you are not using, because this will enable pyplot to properly clean up the memory.

rcParams defines the default values, which can be modified in the matplotlibrc file.
