==============================
Lines with a ticked patheffect
==============================

Ticks can be added along a line to mark one side as a barrier using
`~matplotlib.patheffects.TickedStroke`.  You can control the angle,
spacing, and length of the ticks.

The ticks will also appear appropriately in the legend.
