.. _color-color_cycle_demo: color example code: color_cycle_demo.py ======================================= .. plot:: /home/tcaswell/source/p/matplotlib/doc/mpl_examples/color/color_cycle_demo.py :: """ Demo of custom property-cycle settings to control colors and such for multi-line plots. This example demonstrates two different APIs: 1. Setting the default rc-parameter specifying the property cycle. This affects all subsequent axes (but not axes already created). 2. Setting the property cycle for a specific axes. This only affects a single axes.
