title: Simplest way to plot 3d surface given 3d points
body: <p>I have a lot (289) of 3d points with xyz coordinates which looks like:</p>
  
  <p><img src="https://i.stack.imgur.com/Ug1Rh.png" alt="3D points"></p>
  
  <p>With plotting simply 3d space with points is OK, but I have trouble with surface
  There are some points:</p>
  
  <pre><code>for i in range(30):
          output.write(str(X[i])+' '+str(Y[i])+' '+str(Z[i])+'\n')

  <p>There is no equal X's and Y's values. X is from -0.8 to 0.8, Y is from -0.9 to 0.9 and z from 0 to 111.</p>
  
  <p>If it is possible, how to make 3d surface plot using these points?</p>
