"""
Choosing the thumbnail figure
=============================
This example demonstrates how to choose the figure that is displayed as the
thumbnail, if the example generates more than one figure. This is done by
specifying the keyword-value pair
``sphinx_gallery_thumbnail_number = <fig number>`` as a
comment somewhere below the docstring in the example file. In this example, we
specify that we wish for the second figure to be the thumbnail.
