==================
Parasite axis demo
==================

This example demonstrates the use of parasite axis to plot multiple datasets
onto one single plot.

Notice how in this example, *par1* and *par2* are both obtained by calling
``twinx()``, which ties their x-limits with the host's x-axis. From there, each
of those two axis behave separately from each other: different datasets can be
plotted, and the y-limits are adjusted separately.

This approach uses `mpl_toolkits.axes_grid1.parasite_axes.host_subplot` and
`mpl_toolkits.axisartist.axislines.Axes`.

The standard and recommended approach is to use instead standard Matplotlib
axes, as shown in the :doc:`/gallery/spines/multiple_yaxis_with_spines`
example.

An alternative approach using `mpl_toolkits.axes_grid1.parasite_axes.HostAxes`
and `mpl_toolkits.axes_grid1.parasite_axes.ParasiteAxes` is shown in the
:doc:`/gallery/axisartist/demo_parasite_axes` example.
