==========================
Multiple Yaxis With Spines
==========================

Create multiple y axes with a shared x axis. This is done by creating
a `~.axes.Axes.twinx` axes, turning all spines but the right one invisible
and offset its position using `~.spines.Spine.set_position`.

Note that this approach uses `matplotlib.axes.Axes` and their
`~matplotlib.spines.Spine`\s. An alternative approach for parasite
axes is shown in the :doc:`/gallery/axisartist/demo_parasite_axes` and
:doc:`/gallery/axisartist/demo_parasite_axes2` examples.
