color_cycle deprecated
In light of the new property cycling feature, the Axes method set_color_cycle is now deprecated. Calling this method will replace the current property cycle with one that cycles just the given colors.
Similarly, the rc parameter axes.color_cycle is also deprecated in lieu of the new axes.prop_cycle parameter. Having both parameters in the same rc file is not recommended as the result cannot be predicted. For compatibility, setting axes.color_cycle will replace the cycler in axes.prop_cycle with a color cycle. Accessing axes.color_cycle will return just the color portion of the property cycle, if it exists.
