python - matplotlib colororder and twinx -

i adjusted colororder plot rcparams['axes.color_cycle'] = [some nice , chosen colours]

but when utilize twinx sec axes colororder reset:

matplotlib import pyplot plt matplotlib import rcparams rcparams['axes.color_cycle'] = ['r','g','k'] fig = plt.figure() ax = fig.add_subplot(1,1,1) ax1 = plt.twinx(ax) ax.plot([1,2,3],[4,5,6]) ax.plot([1,2,3],[7,6,4]) ax1.plot([1,2,3],[5,3,1])

is there way circumvent that? line plotted on ax1 should black.

here's way advance color-order sec axis.

from matplotlib import pyplot plt matplotlib import rcparams rcparams['axes.color_cycle'] = ['r','g','k'] fig = plt.figure() ax = fig.add_subplot(1,1,1) ax1 = plt.twinx(ax) line = [] line.append(ax.plot([1,2,3],[4,5,6])[0]) line.append(ax.plot([1,2,3],[7,6,4])[0]) advance in range(len(line)): ax1._get_lines.color_cycle.next() ax1.plot([1,2,3],[5,3,1])

if run example, line on sec axis black.

what happens this:

in line maintain track of numer of lines have plotted on first axis. note, need append first entry of matplotlib.lines.line2d object, hence [0] @ end of ax.plot([1,2,3],[4,5,6]) the for-loop may bit clumsy. however, advances color-cycle of sec axis number of lines have on first axis. done through calling next() on ax1._get_lines.color_cycle you don't acutally need loop counter advance, however, makes code more readable. now, lines on sec axis go on next color in cycle after 1 left off on first axis. if wanted go first axis, you'd have count number of lines on ax1, too.

an interesting question read in context is: get matplotlib color cycle state
