subplots

Wrapper for matplotlib functions for subplots.

hide_empty_axes(axs=None)

Hide empty axes.

Loop over all axes and hide empty ones.

Parameters:

  • axs (mpl.axes.Axes or list of, default: None ) –

    Specify matplotlib.axes.Axes to check for empty state. Default use all of current figure.

label_outer(axs=None)

Only show outer labels and tick labels.

This checks for outest visible axes only. Works only with single Gridspec.

Parameters:

  • axs (mpl.axes.AxesSubplot or list of, default: None ) –

    Specify matplotlib.axes.Axes to check for labeling only outer. Default use all of current figure.

subplot_labels(*, fig=None, xlabel=None, ylabel=None)

Add global labels for subplots.

This method adds shared x- and y-labels for a grid of subplots. These can be created by, e.g. fig, axs = plt.subplots(...).

Parameters:

  • fig (matplotlib figure, default: None ) –

    If None the current figure will be used instead.

  • xlabel (str, default: None ) –

    String of x label.

  • ylabel (str, default: None ) –

    String of y label.
