=================
Annotating a plot
=================
This example shows how to annotate a plot with an arrow pointing to provided
coordinates. We modify the defaults of the arrow, to "shrink" it.
For a complete overview of the annotation capabilities, also see the
:ref:`annotation tutorial<annotations>`.
