    """
    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.
