"""
Diagonal tick labels
=====================

``tick_params(labelrotation=...)`` angles the tick labels instead of leaving
them horizontal -- the standard fix once category names are long enough to
run into their neighbors. The top row plots the *same* long department names
with and without it; the bottom row does the same for short month
abbreviations, to show a modest rotation is a reasonable default even when
the labels were never going to collide -- it just reads as a stylistic
tilt rather than a fix for anything.

A nonzero ``labelrotation`` also right-anchors the label against its own
tick (unlike matplotlib, which needs a separate ``ha="right"`` for this) --
tilted text centered on its tick just leans oddly rather than reading
naturally, so there's no reason to make that a second setting.
