+Demo of custom color-cycle settings to control colors for multi-line plots.
+
+This example demonstrates two different APIs:
+
+    1. Setting the default rc-parameter specifying the color cycle.
+       This affects all subsequent plots.
+    2. Setting the color cycle for a specific axes. This only affects a single
+       axes.
