我可以在 matplotlib 中循环显示线条样式吗 [英] Can i cycle through line styles in matplotlib

问题描述

我知道如何在 matplotlib 中循环显示颜色列表.但是是否可以对线条样式(普通、虚线、虚线等)做类似的事情?我需要这样做，以便我的图表在打印时更容易阅读.任何建议如何做到这一点?

I know how to cycle through a list of colors in matplotlib. But is it possible to do something similar with line styles (plain, dotted, dashed, etc.)? I'd need to do that so my graphs would be easier to read when printed. Any suggestions how to do that?

推荐答案

这样的事情可能会奏效:

Something like this might do the trick:

import matplotlib.pyplot as plt
from itertools import cycle
lines = ["-","--","-.",":"]
linecycler = cycle(lines)
plt.figure()
for i in range(10):
    x = range(i,i+10)
    plt.plot(range(10),x,next(linecycler))
plt.show()

结果:

编辑更新版本 (v2.22)

import matplotlib.pyplot as plt
from cycler import cycler
#
plt.figure()
for i in range(5):
    x = range(i,i+5)
    linestyle_cycler = cycler('linestyle',['-','--',':','-.'])
    plt.rc('axes', prop_cycle=linestyle_cycler)
    plt.plot(range(5),x)
    plt.legend(['first','second','third','fourth','fifth'], loc='upper left', fancybox=True, shadow=True)
plt.show()
