matplotlib.gridspec.GridSpecBase

class matplotlib.gridspec.GridSpecBase(nrows, ncols, height_ratios=None, width_ratios=None) [source]

Bases: object

A base class of GridSpec that specifies the geometry of the grid that a subplot will be placed.

Parameters:
nrows, ncolsint

The number of rows and columns of the grid.

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_geometry(self) [source]

Return a tuple containing the number of rows and columns in the grid.

get_grid_positions(self, fig, raw=False) [source]

Return the positions of the grid cells in figure coordinates.

Parameters:
figFigure

The figure the grid should be applied to. The subplot parameters (margins and spacing between subplots) are taken from fig.

rawbool, default: False

If True, the subplot parameters of the figure are not taken into account. The grid spans the range [0, 1] in both directions without margins and there is no space between grid cells. This is used for constrained_layout.

Returns:
bottoms, tops, lefts, rightsarray

The bottom, top, left, right positions of the grid cells in figure coordinates.

get_height_ratios(self) [source]

Return the height ratios.

This is None if no height ratios have been set explicitly.

get_subplot_params(self, figure=None) [source]
get_width_ratios(self) [source]

Return the width ratios.

This is None if no width ratios have been set explicitly.

property ncols

The number of columns in the grid.

new_subplotspec(self, loc, rowspan=1, colspan=1) [source]

Create and return a SubplotSpec instance.

Parameters:
loc(int, int)

The position of the subplot in the grid as (row_index, column_index).

rowspan, colspanint, default: 1

The number of rows and columns the subplot should span in the grid.

property nrows

The number of rows in the grid.

set_height_ratios(self, height_ratios) [source]

Set the relative heights of the rows.

height_ratios must be of length nrows. Each row gets a relative height of height_ratios[i] / sum(height_ratios).

set_width_ratios(self, width_ratios) [source]

Set the relative widths of the columns.

width_ratios must be of length ncols. Each column gets a relative width of width_ratios[i] / sum(width_ratios).
