Lines with a ticked patheffect#

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

The ticks will also appear appropriately in the legend.

ax.plot(x, y, label="Curve", path_effects=[patheffects.withTickedStroke()])
