For the most part, in v1.5.x, the cycler will only work where-ever color
cycling worked before. For the 2.0 release and beyond, we are working on
getting more plots to support using the cycler features. Now, if you find a
situation where color cycling works but other properties won't cycle, then
that is most likely a real bug (except for pie()...).

I cannot get the new prop cycler to work with bar plots, it does not pick
up the cycler properties at all.

I have minimally adapted the cycler demo
https://github.com/matplotlib/matplotlib/blob/0037595096e3be3ec863f3e3008e73c469e2f2b8/examples/color/color_cycle_demo.py
to show this. Running this gives two blue and one red bar plot, when it
should give (in my expectation) one cyan, one magenta (from the cycle) and
one red (manually set).

from cycler import cycler
import numpy as np
import matplotlib.pyplot as plt

x = np.linspace(0, 2 * np.pi)
offsets = np.linspace(0, 2*np.pi, 4, endpoint=False)

Create array with shifted-sine curve along each column

yy = np.transpose([np.sin(x + phi) for phi in offsets])

plt.rc('lines', linewidth=4)
plt.rc('axes', prop_cycle=(cycler('color', ['r', 'g', 'b', 'y']) +
cycler('linestyle', ['-', '--', ':', '-.'])))
fig, (ax0, ax1) = plt.subplots(nrows=2)
ax0.plot(yy)
ax0.set_title('Set default color cycle to rgby')

ax1.set_prop_cycle(cycler('color', ['c', 'm', 'y', 'k']) +
cycler('lw', [1, 2, 3, 4]))

ax1.plot(yy) # original

ax1.bar(x, yy[:,1]) # a simple bar plot from the available data
ax1.bar(x, yy[:,2]) # both these come out as blue
ax1.bar(x, yy[:,3], color='r') # this works, gives red bars, so "color" is recognized!
ax1.set_title('Set axes color cycle to cmyk')

Tweak spacing between subplots to prevent labels from overlapping

plt.subplots_adjust(hspace=0.3)
plt.show()

This is on mpl 1.5.1. Is this pebkac, or does the cycler only work for
some plots (if so, which ones)?

#5674 addresses this issue (and others).

@WeatherGod: Why do you call out pie. #5674 fixes pie as well?

Right, I was talking about whatever has been released.

OK, so bar plots basically can't digest cycles if I understand correctly. Thanks, I missed that.

#5674 addresses this issue.

really, how? It only talks about colors afaict, but not about property cycles (which can have properties other than color, e.g. hatch) for bar plots, if I haven't missed something?

@WeatherGod should I close this, then, or leave it open until next-major-release?

awesome, thanks!
