Set figure.hooks: mpl_azhooks:context_axes_edit in your matplotlibrc file
to register a context menu action on right click to trigger the Qt figure
options widget on the clicked Axes (useful when working with figures with
many subplots).
Set figure.hooks: mpl_azhooks:small_qt_icons to make the default Qt toolbar
icons smaller (useful when working with small figures, in particular to leave
more room for the coordinates display on the right).
Set figure.hooks: mpl_azhooks:black_canvas to make the background Qt widget
canvas black (useful when using a dark theme (with white lines) on a
transparent matplotlib figure, e.g. for making figures that will ultimately be
displayed on a dark-background document) -- this setting more likely to be set
via mpl.rcParams["figure.hooks"] = "mpl_azhooks:black_canvas" together with
a mpl.style.use call.
