matplotlib.pyplot.subplot_mosaic

matplotlib.pyplot.subplot_mosaic(layout, *, subplot_kw=None, gridspec_kw=None, empty_sentinel='.', **fig_kw)

Build a layout of Axes based on ASCII art or nested lists.

This is a helper function to build complex GridSpec layouts visually.

Note

This API is provisional and may be revised in the future based on early user feedback.

Parameters:

layoutlist of list of {hashable or nested} or str

A visual layout of how you want your Axes to be arranged labeled as strings. For example

x = [['A panel', 'A panel', 'edge'],
     ['C panel', '.',       'edge']]

Produces 4 axes:

• 'A panel' which is 1 row high and spans the first two columns
• 'edge' which is 2 rows high and is on the right edge
• 'C panel' which in 1 row and 1 column wide in the bottom left
• a blank space 1 row and 1 column wide in the bottom center

Any of the entries in the layout can be a list of lists of the same form to create nested layouts.

If input is a str, then it must be of the form

'''
AAE
C.E
'''

where each character is a column and each line is a row. This only allows only single character Axes labels and does not allow nesting but is very terse.

subplot_kwdict, optional

Dictionary with keywords passed to the Figure.add_subplot call used to create each subplot.

gridspec_kwdict, optional

Dictionary with keywords passed to the GridSpec constructor used to create the grid the subplots are placed on.

empty_sentinelobject, optional

Entry in the layout to mean "leave this space empty". Defaults to '.'. Note, if layout is a string, it is processed via inspect.cleandoc to remove leading white space, which may interfere with using white-space as the empty sentinel.

**fig_kw

All additional keyword arguments are passed to the pyplot.figure call.

Returns:

figFigure

The new figure

dict[label, Axes]

A dictionary mapping the labels to the Axes objects.
