有没有办法加载图像文件并将其用作matplotlib圆形补丁创建的圆圈的背景图像?
import matplotlib.pyplot as plt
from matplotlib.patches import Circle
fig = plt.figure(figsize=(10,10))
ax = fig.add_subplot(111)
ci = Circle((2, -2), 5)
ax.add_patch(ci)
ax.annotate('1', xy=(2, -2), xycoords = 'data', xytext=(-2, 3),size=20, textcoords='data', arrowprops=dict(arrowstyle="fancy", fc="0.8", ec="0.6", patchB=el,connectionstyle="angle3,angleA=0,angleB=-90"),)
plt.show()
换句话说,我希望这个图中的圆圈有一个图像作为背景:
