三维散点图：
X1 = np.array([
[0, 0, 0],
[2, 0, 0],
[2, 0, 1],
[1, 2, 0]
])
X2 = np.array([
[0, 0, 1],
[0, 1, 0],
[0, -2, 1],
[1, 1, -2]
])
fig = plt.figure()
ax = fig.gca(projection="3d")
ax.scatter(X1[:, 0], X1[:, 1], zs=X1[:, 2], zdir="z", c="#00DDAA", marker="o", s=40)
ax.scatter(X2[:, 0], X2[:, 1], zs=X2[:, 2], zdir="z", c="#FF5511", marker="^", s=40)
ax.set(xlabel="X", ylabel="Y", zlabel="Z")
plt.show()
结果如下：
