示例，

import numpy as np
import matplotlib.pyplot as plt
  
fig = plt.figure(figsize = (8, 8))
ax = plt.axes(projection = '3d')
  
# Data for a three-dimensional line
z = np.linspace(0, 15, 1000)
x = np.sin(z)
y = np.cos(z)
ax.plot3D(x, y, z, 'green')
plt.show()
plt.show()

如图：

view_init() 视角转换

函数定义如：

view_init(elev=None, azim=None, vertical_axis='z')

其中，elev - elevated angle，仰角；azim - horizontal angle，水平视角.

示例如，

import numpy as np
import matplotlib.pyplot as plt
  
fig = plt.figure(figsize = (8, 8))
ax = plt.axes(projection = '3d')
  
# Data for a three-dimensional line
z = np.linspace(0, 15, 1000)
x = np.sin(z)
y = np.cos(z)
ax.plot3D(x, y, z, 'green')

#视角
#ax.view_init(120, 30, 'x')
#ax.view_init(120, 30, 'y')
ax.view_init(120, 30, 'z')
  
plt.show()
