我可以在matplotlib中循环浏览线型吗 [英] Can i cycle through line styles in matplotlib

问题描述

我知道如何在matplotlib中循环浏览颜色列表.但是是否可以对线条样式执行类似的操作(纯文本，点划线，虚线等)?我需要这样做，这样我的图形在打印时将更易于阅读.有什么建议可以做到吗?

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

类似这样的方法可能会解决问题:

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()
