将yerr/xerr绘制为阴影区域而不是误差线 [英] Plot yerr/xerr as shaded region rather than error bars

问题描述

在matplotlib中，如何将错误绘制为阴影区域而不是错误条?

In matplotlib, how do I plot error as a shaded region rather than error bars?

推荐答案

忽略示例图中各点之间的平滑插值(这需要进行一些手动插值，或者只是具有更高的数据分辨率)，您可以使用 pyplot.fill_between() :

Ignoring the smooth interpolation between points in your example graph (that would require doing some manual interpolation, or just have a higher resolution of your data), you can use pyplot.fill_between():

from matplotlib import pyplot as plt
import numpy as np

x = np.linspace(0, 30, 30)
y = np.sin(x/6*np.pi)
error = np.random.normal(0.1, 0.02, size=y.shape)
y += np.random.normal(0, 0.1, size=y.shape)

plt.plot(x, y, 'k-')
plt.fill_between(x, y-error, y+error)
plt.show()

另请参见 matplotlib示例.
