title: matplotlib (mplot3d) - how to increase the size of an axis (stretch) in a 3D Plot?
body: <p>I have this so far:</p>
  
  <pre><code>x,y,z = data.nonzero()    
  fig = plt.figure()
  ax = fig.add_subplot(111, projection='3d')
  ax.scatter(x, y, z, zdir='z', c= 'red')
  plt.savefig("plot.png")
  </code></pre>
  
  <p>Which creates:
  <img src="https://i.stack.imgur.com/HKQVl.png" alt="enter image description here"></p>
  
  <p>What I'd like to do is stretch this out to make the Z axis 9 times taller and keep X and Y the same.  I'd like to keep the same coordinates though.</p>
  
  <p>So far I tried this guy:</p>
  
  <pre><code>fig = plt.figure(figsize=(4.,35.))
  </code></pre>
  
  <p>But that just stretches out the plot.png image.  </p>
