"""
=================================================================
Implemented support for prop_cycle property markevery in rcParams
=================================================================
This example demonstrates a working solution to issue #8576, providing full
support of the markevery property for axes.prop_cycle assignments through
rcParams. Makes use of the same list of markevery cases from the
:doc:`markevery demo
</gallery/lines_bars_and_markers/markevery_demo>`.
Renders a plot with shifted-sine curves along each column with
a unique markevery value for each sine curve.
