获取默认的线条颜色周期 [英] Get default line colour cycle

问题描述

当您绘制第一行时，我注意到第一行是蓝色，然后是绿色，然后是红色，依此类推.

I noticed when you plot that the first line is blue, then green, then red, and so on.

是否有某种方法可以访问此颜色列表?我已经看过一百万篇关于如何更改颜色循环或访问迭代器的文章，但没有关于如何获取默认情况下matplotlib循环通过的颜色列表的文章.

Is there some way to access this list of colours? I've seen a million posts on how to change the colour cycle or access the iterator, but not on how to just get the list of colours that matplotlib cycles through by default.

推荐答案

在matplotlib版本> = 1.5中，可以打印名为axes.prop_cycle的rcParam:

In matplotlib versions >= 1.5, you can print the rcParam called axes.prop_cycle:

print plt.rcParams['axes.prop_cycle'].by_key()['color']

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

或等效地，在python3中:

print(plt.rcParams['axes.prop_cycle'].by_key()['color'])

在版本中< 1.5，这称为color_cycle:

In versions < 1.5, this was called color_cycle:

print plt.rcParams['axes.color_cycle']

# [u'b', u'g', u'r', u'c', u'm', u'y', u'k']

请注意，默认颜色周期在版本2.0.0中已更改 http://matplotlib.org/users/dflt_style_changes.html#colors-in-default-property-cycle

Note that the default color cycle changed in version 2.0.0 http://matplotlib.org/users/dflt_style_changes.html#colors-in-default-property-cycle
