Bug summary

When updating from version 3.5.0 to 3.6.2, the default plot color cycler changed and there's no documentation indicating it should have.

Code for reproduction

import matplotlib.pyplot as plt
plt.style.use('_mpl-gallery')
fig, ax = plt.subplots()
for num in [1, 2, 3, 4]:
    ax.plot(0, num, 'o')

plt.show()

Actual outcome

Expected outcome

Additional information

Documentation says that the default cycler should be:

('color', ['#1f77b4', '#ff7f0e', '#2ca02c', '#d62728', '#9467bd', '#8c564b', '#e377c2', '#7f7f7f', '#bcbd22', '#17becf'])

It displays expected colors in version 3.5.0, but not in version 3.6.2.

Found fix:

import matplotlib as mpl
from cycler import cycler
mpl.rcParams['axes.prop_cycle'] = cycler('color', [ '#1f77b4', '#ff7f0e', '#2ca02c', '#d62728', '#9467bd', '#8c564b', '#e377c2', '#7f7f7f', '#bcbd22', '#17becf'])

But that should not be necessary as that should be the default
