=====
Ticks
=====

In mpltern, tick markers, tick labels, and grid lines are plotted based on
`ax.get_{t,l,r}axis_transform()` like `ax.get_{x,y}axis_transform()` in
Matplotlib.

For `ax.get_taxis_transform()`, for example, the first coordinate is for the
t-axis values. For the second coordinate, 0 and 1 corresponds to the
`"tick1"` and the `"tick2"` positions, respectively.
Therefore, for the t-axis value of *t*, the tick-marker positions of `"tick1"`
and `"tick2"` are given by (*t*, 0) and (*t*, 1), respectively, and the grid
line spans between (*t*, 0) and (*t*, 1).

Using these transforms, we can e.g. plot the region where the ratio of *l* and
*r* is in a certain range in a bit sementic way as follows.
