Function axes(figure=None, ax=None, **fig_kw) -> matplotlib.axes._axes.Axes

Return a set of Axes.

Parameters:

• figure: optional Figure from which to obtain the Axes or an (x,y) figure size or an (x,y,dpi) figure size
• ax: optional Axes or axes index

If ax is already an Axes it is returned unchanged. Otherwise ax should be the index of a set of axes, default 0.

If figure is a Figure, ax is used to select one of its sets of axes.

Otherwise a Figure is created and a set of axes is selected. The default figure size comes from DEFAULT_FIGURE_SIZE ((10, 7)) and the default dpi comes from DEFAULT_FIGURE_DPI (100). The figure positional parameter may be supplied as a 2-tuple (fig_dx,fig_dy) to override the default size or as a 3-tuple (fig_dx,fig_dy,dpi) to override the default size and dpi.

Function print_figure(figure_or_ax, imgformat=None, file=None)

Print figure_or_ax to a file.

Parameters:

• figure_or_ax: a matplotlib.figure.Figure or an object with a .figure attribute such as a set of Axes
• imgformat: optional output format; if omitted use 'sixel' if file is a terminal, otherwise 'png'
• file: the output file, default sys.stdout

Function remove_decorations(figure_or_ax: Union[matplotlib.figure.Figure, matplotlib.axes._axes.Axes])

Remove all decorations from a Figure or Axes instance, intended for making bare plots such as a tile in GUI.

Presently this removes:

• axes markings and legend from each axis
• the padding from all the figure subplots

Function save_figure(figure_or_ax, imgpath: str, force=False)

Save a Figure to the file imgpath.

Parameters:

• figure_or_ax: a matplotlib.figure.Figure or an object with a .figure attribute such as a set of Axes
• imgpath: the filesystem path to which to save the image
• force: optional flag, default False: if true the imgpath will be written to even if it exists

Function saved_figure(figure_or_ax, dir=None, ext=None)

Context manager to save a Figure to a file and yield the file path.

Parameters:

• figure_or_ax: a matplotlib.figure.Figure or an object with a .figure attribute such as a set of Axes
• dir: passed to tempfile.TemporaryDirectory
• ext: optional file extension, default 'png'
