Matplotlib: boxplot

• 1. 模块：matplotlib.pyplot
• 2. 方法：boxplot()

1. 基础绘图

import matplotlib.pyplot as plt
import numpy as np

plt.style.use('_mpl-gallery')   '#设置绘图格式

# make data:
np.random.seed(10)
D = np.random.normal((3, 5, 4), (1.25, 1.00, 1.25), (100, 3))   #构建数据

# plot
fig, ax = plt.subplots()   #构建画板和画布
VP = ax.boxplot(D, positions=[2, 4, 6], widths=1.5, patch_artist=True,
                showmeans=False, showfliers=False,
                medianprops={"color": "white", "linewidth": 0.5},
                boxprops={"facecolor": "C0", "edgecolor": "white",
                          "linewidth": 0.5},
                whiskerprops={"color": "C0", "linewidth": 1.5},
                capprops={"color": "C0", "linewidth": 1.5})   #对画布 ax 调用方法 boxplot

ax.set(xlim=(0, 8), xticks=np.arange(1, 8),
       ylim=(0, 8), yticks=np.arange(1, 8))

plt.show()   #展示图像，示例一
