关于python：在matplotlib中使用图像作为刻度标签

Using an image for tick labels in matplotlib

本问题已经有最佳答案，请猛点这里访问。

我有一系列固定宽度的小图像，我想用它们替换刻度标签。例如，考虑以下最小的工作示例：

1
2
3
4
5
6
7

import numpy as np
import pylab as plt

A = np.random.random(size=(5,5))
fig, ax = plt.subplots(1, 1)
ax.matshow(A)
plt.show()

enter

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21

import numpy as np
import matplotlib.pyplot as plt
import matplotlib.image as mpimg
import pylab as pl

A = np.random.random(size=(5,5))
fig, ax = plt.subplots(1, 1)

xl, yl, xh, yh=np.array(ax.get_position()).ravel()
w=xh-xl
h=yh-yl
xp=xl+w*0.1 #if replace ‘0’ label, can also be calculated systematically using xlim()
size=0.05

img=mpimg.imread(‘microblog.png’)
ax.matshow(A)
ax1=fig.add_axes([xp-size*0.5, yh, size, size])
ax1.axison = False
imgplot = ax1.imshow(img,transform=ax.transAxes)

plt.savefig(‘temp.png’)

enter
