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 layoutbox.

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(self, figure=None)[source]

Return the SubplotParams for the GridSpec.

In order of precedence the values are taken from

locally_modified_subplot_params(self)[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(self, 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(self, **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.
