Parameters a Series, 1d-array, or list. I think that @mpetroff's point (please correct me if I am wrong) was more that having a not-so-great default (qualitative) color cycle makes a significant number of the plots made with Matplotlib 2 difficult to read for quite a lot of people (including him), as I guess most of the end-users simply rely on the default color cycle. This basically means you can call the set_color_cycle with None as the only argument, and it will be replaced with the default cycle found in rcParams['axes. The Axes is the area on which data is plotted. Line chart examples. # matplotlib color string, such as r, k, or b - an rgb tuple, such as # (1. Default is *True*.
