水印图片#

通过将其移到前面(zorder=3)并使其半透明(alpha=0.7),在图上覆盖一张图片。

import matplotlib.pyplot as plt
import numpy as np

import matplotlib.cbook as cbook
import matplotlib.image as image

with cbook.get_sample_data('logo2.png') as file:
    im = image.imread(file)

fig, ax = plt.subplots()

np.random.seed(19680801)
x = np.arange(30)
y = x + np.random.randn(30)
ax.bar(x, y, color='#6bbc6b')
ax.grid()

fig.figimage(im, 25, 25, zorder=3, alpha=.7)

plt.show()
watermark image
