pansas 绘制定制的箱线图

1  普通风格

代码

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt

plt.rcParams['font.sans-serif'] = 'SimHei'   # 使图形中的中文正常编码显示
plt.rcParams['axes.unicode_minus'] = False   # 使坐标轴刻度表签正常显示正负号

rng = np.random.RandomState(27)
x = rng.normal(loc=0, scale=1.5, size=9000)

df = pd.DataFrame([x, x+1.5]).T
df.columns=['甲', '乙']

df.plot(kind='box')

plt.show()
