Parasite axis demo

This example demonstrates the use of parasite axis to plot multiple datasets
7+
onto one single plot.
78
8-
The following code is an example of a parasite axis. It aims to show how
9-
to plot multiple different values onto one single plot. Notice how in this
10-
example, par1 and par2 are both calling twinx meaning both are tied directly to
11-
the x-axis. From there, each of those two axis can behave separately from the
12-
each other, meaning they can take on separate values from themselves as well as
13-
the x-axis.
9+
Notice how in this example, *par1* and *par2* are both obtained by calling
10+
``twinx()``, which ties their x-limits with the host's x-axis. From there, each
11+
of those two axis behave separately from each other: different datasets can be
12+
plotted, and the y-limits are adjusted separately.
