mpl.rcParams['axes.prop_cycle'] = cycler(color=['r', 'g', 'b', 'y'])

# Matplotlib also provides a couple of convenience functions for modifying rc
# settings. The :func:`matplotlib.rc` command can be used to modify multiple
# settings in a single group at once, using keyword arguments:

mpl.rc('lines', linewidth=4, color='g')
mpl.rc('lines', linewidth=4, linestyle='-.')
plt.plot(data)
