===============================
Resizing axes with tight layout
===============================

`~.figure.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 :doc:`/tutorials/intermediate/tight_layout_guide` for more details and
:doc:`/tutorials/intermediate/constrainedlayout_guide` for an alternative.
