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.
