title: How can I make a simple 3D line with Matplotlib?
body: <p>I want to generate the lines, which I get from an array in 3D.</p>
  
  <p>Here is the code:</p>
  
  <pre><code>VecStart_x = [0,1,3,5]
  VecStart_y = [2,2,5,5]
  VecStart_z = [0,1,1,5]
  VecEnd_x = [1,2,-1,6]
  VecEnd_y = [3,1,-2,7]
  VecEnd_z  =[1,0,4,9]
  
  import matplotlib.pyplot as plt
  from mpl_toolkits.mplot3d import Axes3D
  fig = plt.figure()
  ax = fig.add_subplot(111, projection='3d')
  
  ax.plot([VecStart_x ,VecEnd_x],[VecStart_y,VecEnd_y],[VecStart_z,VecEnd_z])
  plt.show()
  Axes3D.plot()
  </code></pre>
  
  <p>I get that error:</p>
  
  <blockquote>
    <p>ValueError: third arg must be a format string</p>
  </blockquote>
