        "\n# Multiple y-axis with Spines\n\nCreate multiple y axes with a shared x-axis. This is done by creating\na `~.axes.Axes.twinx` Axes, turning all spines but the right one invisible\nand offset its position using `~.spines.Spine.set_position`.\n\nNote that this approach uses `matplotlib.axes.Axes` and their\n`~matplotlib.spines.Spine`\\s.  Alternative approaches using non-standard Axes\nare shown in the :doc:`/gallery/axisartist/demo_parasite_axes` and\n:doc:`/gallery/axisartist/demo_parasite_axes2` examples.\n\n.. redirect-from:: /gallery/spines/multiple_yaxis_with_spines\n"
