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, 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.

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

Optionally use a custom Figure instance.

clearbool, default: False

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

tight_layoutbool or dict, default: rcParams["figure.autolayout"] (default: False)

If False use subplotpars. If True adjust subplot parameters using tight_layout with default padding. When providing a dict containing the keys pad, w_pad, h_pad, and rect, the default tight_layout paddings will be overridden.

constrained_layoutbool, default: rcParams["figure.constrained_layout.use"] (default: False)

If True use constrained layout to adjust positioning of plot elements. Like tight_layout, but designed to be more flexible. See Constrained Layout Guide for examples. (Note: does not work with add_subplot or subplot2grid.)

**kwargs : optional

See Figure for other possible arguments.

Returns

Figure

The Figure instance returned will also be passed to new_figure_manager in the backends, which allows to hook custom Figure classes into the pyplot interface. Additional kwargs will be passed to the Figure init function.

Notes

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.
