=============================
Resize Axes with tight layout
=============================

`~.Figure.tight_layout` attempts to resize subplots in a figure so that there
are no overlaps between Axes objects and labels on the Axes.

See :ref:`tight_layout_guide` for more details and
:ref:`constrainedlayout_guide` for an alternative.
