python箱形图各部分含义_python – 箱形图中框的面部图案

重要的方面是在调用boxplot时设置patch_artist = True.

import numpy as np

import matplotlib.pyplot as plt

# fake up some data

spread= np.random.rand(50) * 100

center = np.ones(25) * 50

flier_high = np.random.rand(10) * 100 + 100

flier_low = np.random.rand(10) * -100

data = np.concatenate((spread, center, flier_high, flier_low), 0)

# basic plot

bp = plt.boxplot(data, patch_artist=True)

for box in bp['boxes']:

# change outline color

box.set(color='red', linewidth=2)

# change fill color

box.set(facecolor = 'green' )

# change hatch

box.set(hatch = '/')

plt.show()

基本的绘图示例取自boxplot demo.但是,这些示例都没有设置patch_artist = True.如果省略该语句,您将收到此错误：

AttributeError: ‘Line2D’ object has no attribute ‘set_facecolor’

boxplot demo 2非常详细地展示了如何将矩形拟合到箱线图以获得着色. This blog指向patch_artist的选项.
