Toggle minorticks on Axis
2+
------------------------------

4+
Minor ticks on an `~matplotlib.axis.Axis` can be displayed or removed using
5+
`~matplotlib.axis.Axis.minorticks_on` and `~matplotlib.axis.Axis.minorticks_off`;
6+
e.g.: ``ax.xaxis.minorticks_on()``. See also `~matplotlib.axes.Axes.minorticks_on`.
