不规则X-Y-Z-d的等高线/imshow图

Answer 1

plt.tricontourf(x,y,z)是否满足您的要求？

它将绘制不规则间距数据（非直线网格）的填充等高线。

您可能还需要查看plt.tripcolor()。

import numpy as np
import matplotlib.pyplot as plt
x = np.random.rand(100)
y = np.random.rand(100)
z = np.sin(x)+np.cos(y)
f, ax = plt.subplots(1,2, sharex=True, sharey=True)
ax[0].tripcolor(x,y,z)
ax[1].tricontourf(x,y,z, 20) # choose 20 contour levels, just to show how good its interpolation is
ax[1].plot(x,y, 'ko ')
ax[0].plot(x,y, 'ko ')
plt.savefig('test.png')
