使用 matplotlib 绘制箱线图

使用 matplotlib 绘制箱线图的示例

import numpy as np
import matplotlib.pyplot as plt


fig = plt.figure(figsize=(8, 5))
axes = plt.subplot(111)

n = 5
Z = np.zeros((n, 4))
X = np.linspace(0, 2, n)
rng = np.random.default_rng()
Y = rng.random((n, 4))
plt.boxplot(Y)

plt.xticks([])
plt.yticks([])


# Add a title and a box around it
from matplotlib.patches import FancyBboxPatch

ax = plt.gca()
ax.add_patch(
    FancyBboxPatch(
        (-0.05, 0.87),
        width=0.66,
        height=0.165,
        clip_on=False,
        boxstyle="square,pad=0",
        zorder=3,
        facecolor="white",
        alpha=1.0,
        transform=plt.gca().transAxes,
    )
)

plt.text(
    -0.05,
    1.02,
    " Box Plot:   plt.boxplot(...)\n ",
    horizontalalignment="left",
    verticalalignment="top",
    size="xx-large",
    transform=axes.transAxes,
)

plt.text(
    -0.04,
    0.98,
    "\n Make a box and whisker plot ",
    horizontalalignment="left",
    verticalalignment="top",
    size="large",
    transform=axes.transAxes,
)

plt.show()
