Resize Axes with constrained layout
===================================
*Constrained layout* attempts to resize subplots in
a figure so that there are no overlaps between Axes objects and labels
on the Axes.
See :ref:`constrainedlayout_guide` for more details and
:ref:`tight_layout_guide` for an alternative.
