 baseline method).  The decorator will arrange for setting up the figures and
 then collect the drawn results and compare them.

 It is preferred that new tests use ``style='mpl20'`` as this leads to smaller
 figures and reflects the newer look of default Matplotlib plots. Also, if the
 texts (labels, tick labels, etc) are not really part of what is tested, use
 ``remove_text=True`` as this will lead to smaller figures and reduce possible
 issues with font mismatch on different platforms.

 See the documentation of `~matplotlib.testing.decorators.image_comparison` and
 `~matplotlib.testing.decorators.check_figures_equal` for additional information
 about their use.
