matplotlib.gridspec.GridSpecBase

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

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

Parameters:

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.

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_width_ratios(self) [source]

Return the width ratios.

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

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.
