Secondary Axis
==============

Sometimes we want as secondary axis on a plot, for instance to convert
Sometimes we want a secondary axis on a plot, for instance to convert

axes with only one axis visible via `.Axes.axes.secondary_xaxis` and
`.Axes.axes.secondary_yaxis`. This secondary axis can have a different scale
