您需要使用
extent关键字参数来imshow。
作为一个简单的例子：
import numpy as npimport matplotlib.pyplot as plt# Random points between 50000 and 51000x, y = 1000 * np.random.random((2, 10)) + 50000# A 10x10 "image"...image = np.arange(100).reshape((10,10))# In a lot of cases, image data will be "flipped" vertically, so you may need # use the `origin` kwarg, as well (or just swap the ymin and ymax ordering).plt.imshow(image, extent=[x.min(), x.max(), y.min(), y.max()])plt.plot(x, y, 'ro')plt.show()
