Such axes would share the x scale with a host axes, but show a different scale in y direction. This approach uses `mpl_toolkits.axes_grid1.parasite_axes.HostAxes` and `mpl_toolkits.axes_grid1.parasite_axes.ParasiteAxes`. 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` and `mpl_toolkits.axisartist` is shown in the :doc:`/gallery/axisartist/demo_parasite_axes2` example. ..
