matplotlib._tight_layout
Routines to adjust subplot params so that subplots are nicely fit in the figure. In doing so, only axis labels, tick labels, axes titles and offsetboxes that are anchored to axes are currently considered.
Internally, this module assumes that the margins (left margin, etc.) which are
differences between Axes.get_tightbbox
and Axes.bbox
are independent of
Axes position. This may fail if Axes.adjustable
is datalim
as well as
such cases as when left or right margin are affected by xlabel.
