matplotlib.gridspec.GridSpec#

class matplotlib.gridspec.GridSpec(nrows, ncols, figure=None, left=None, bottom=None, right=None, top=None, wspace=None, hspace=None, width_ratios=None, height_ratios=None)[source]#

Bases: GridSpecBase

A grid layout to place subplots within a figure.

The location of the grid cells is determined in a similar way to SubplotParams using left, right, top, bottom, wspace and hspace.

Indexing a GridSpec instance returns a SubplotSpec.

Parameters:

nrows, ncolsint: The number of rows and columns of the grid.
figureFigure, optional: Only used for constrained layout to create a proper layoutgrid.
left, right, top, bottomfloat, optional: Extent of the subplots as a fraction of figure width or height. Left cannot be larger than right, and bottom cannot be larger than top. If not given, the values will be inferred from a figure or rcParams at draw time. See also GridSpec.get_subplot_params.
wspacefloat, optional: The amount of width reserved for space between subplots, expressed as a fraction of the average axis width. If not given, the values will be inferred from a figure or rcParams when necessary. See also GridSpec.get_subplot_params.
hspacefloat, optional: The amount of height reserved for space between subplots, expressed as a fraction of the average axis height. If not given, the values will be inferred from a figure or rcParams when necessary. See also GridSpec.get_subplot_params.
width_ratiosarray-like of length ncols, optional: Defines the relative widths of the columns. Each column gets a relative width of width_ratios[i] / sum(width_ratios). If not given, all columns will have the same width.
height_ratiosarray-like of length nrows, optional: Defines the relative heights of the rows. Each row gets a relative height of height_ratios[i] / sum(height_ratios). If not given, all rows will have the same height.

get_subplot_params(figure=None)[source]#

Return the SubplotParams for the GridSpec.

In order of precedence the values are taken from

non-None attributes of the GridSpec
the provided figure
rcParams["figure.subplot.*"]

Note that the figure attribute of the GridSpec is always ignored.

locally_modified_subplot_params()[source]#

Return a list of the names of the subplot parameters explicitly set in the GridSpec.

This is a subset of the attributes of SubplotParams.

tight_layout(figure, renderer=None, pad=1.08, h_pad=None, w_pad=None, rect=None)[source]#

Adjust subplot parameters to give specified padding.

Parameters:

figureFigure: The figure.
rendererRendererBase subclass, optional: The renderer to be used.
padfloat: Padding between the figure edge and the edges of subplots, as a fraction of the font-size.
h_pad, w_padfloat, optional: Padding (height/width) between edges of adjacent subplots. Defaults to pad.
recttuple (left, bottom, right, top), default: None: (left, bottom, right, top) rectangle in normalized figure coordinates that the whole subplots area (including labels) will fit into. Default (None) is the whole figure.

update(**kwargs)[source]#

Update the subplot parameters of the grid.

Parameters that are not explicitly given are not changed. Setting a parameter to None resets it to rcParams["figure.subplot.*"].

Parameters:

left, right, top, bottomfloat or None, optional: Extent of the subplots as a fraction of figure width or height.
wspace, hspacefloat, optional: Spacing between the subplots as a fraction of the average subplot width / height.
