Plotting Routines
=================

A simple demonstration of a multi-line *vs.*
image plot with
`domain coloring <https://en.wikipedia.org/wiki/Domain_coloring>`_, nested
inside a figure list.

We specifically test a safety feature that doesn't allow image plots
to have unevenly spaced axes,
and show how to deal with this.

We also show how the equivalent of the color limits can be chosen by setting
the scaling of the image -- notice how data that exceeds the "scaling"
parameter is masked out as white here.
