Placing text boxes
==================

When decorating axes with text boxes, two useful tricks are to place
the text in axes coordinates (see :doc:`/tutorials/advanced/transforms_tutorial`), so the
text doesn't move around with changes in x or y limits.  You can also
use the ``bbox`` property of text to surround the text with a
:class:`~matplotlib.patches.Patch` instance -- the ``bbox`` keyword
argument takes a dictionary with keys that are Patch properties.

            verticalalignment='top', bbox=props)
