python how to draw a 3D figure using a 3D array?

Question

ax = plt.axes(projection ="3d")
plt.figure()

ax.scatter(res[???],s=2,color="red")
plt.show()

res.shape

(3438, 3)

res

array([[-0.37735112,  0.70916688, -0.11611093],
       [-1.65987721,  0.36333406, -0.15776237],

Answer 1

试下这个

import matplotlib.pyplot as plt
import numpy as np

fig = plt.figure()
ax = fig.add_subplot(projection='3d')

ar = np.array([[-0.37735112,  0.70916688, -0.11611093],
       [-1.65987721,  0.36333406, -0.15776237],
       [ 0.04139574, -0.6512135 ,  0.58187669],
       [ 1.70450881,  3.08870729,  0.53986034],
       [-0.31678427, -0.59254118,  0.20142223],
       [-0.21731326, -0.92191064, -0.18022078]])


ax.scatter(ar[:,0], ar[:,1], ar[:,2])

ax.set_xlabel('X Label')
ax.set_ylabel('Y Label')
ax.set_zlabel('Z Label')

plt.show()
