==========================================
Set default x-axis tick labels on the top
==========================================

We can use :rc:`xtick.labeltop` and :rc:`xtick.top` and :rc:`xtick.labelbottom`
and :rc:`xtick.bottom` to control where on the axes ticks and their labels
appear.

These properties can also be set in ``.matplotlib/matplotlibrc``.
