matplotlib错误栏可以设置线型吗? [英] Can matplotlib errorbars have a linestyle set?

问题描述

是否可以将相同的线型设置为 matplotlib 错误栏而不是数据点线型?

Is is possible to set the same linestyle to matplotlib errorbars than to the datapoints linestyle?

在下面的示例中，绘制了两条线，其中一条线由于 ls='-.' 而用虚线表示.范围.但是，误差条是实线.是否可以修改错误栏的样式/外观以匹配结果行?

In the example below, two lines are plotted, one of them is dashed because of the ls='-.' parameter. However, the errorbar are solid lines. Is is possible to modify the style/look of the errorbars to match the results line?

import matplotlib.pyplot as plt
import numpy as np

x = np.array(range(0,10))
y = np.array(range(0,10))
yerr = np.array(range(1,11)) / 5.0
yerr2 = np.array(range(1,11)) / 4.0

y2 = np.array(range(0,10)) * 1.2

plt.errorbar(x, y, yerr=yerr, lw=8, errorevery=2, ls='-.')
plt.errorbar(x, y2, yerr=yerr2, lw=8, errorevery=3)
plt.show()

推荐答案

这很简单，更改错误栏的线型只需要简单的 .set_linestyle 调用:

It is trivial, changing the linestyle of the errorbars only require a simple .set_linestyle call:

eb1=plt.errorbar(x, y, yerr=yerr, lw=2, errorevery=2, ls='-.')
eb1[-1][0].set_linestyle('--') #eb1[-1][0] is the LineCollection objects of the errorbar lines
eb2=plt.errorbar(x, y2, yerr=yerr2, lw=2, errorevery=3)
eb2[-1][0].set_linestyle('-.')
