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: matplotlib.gridspec.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.

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 column 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

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
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 of 4 floats, default: (0, 0, 1, 1), i.e. the whole figure

(left, bottom, right, top) rectangle in normalized figure coordinates that the whole subplots area (including labels) will fit into.

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.
