title: Matlab how to change contourf plot's location on z axis
body: <p>I have a 3d surface in my figure <code>surf(x,y,z)</code></p>
  
  <p>I also have a <code>contourf</code> surface (which is basically a 2D plane).</p>
  
  <p>I plot them in the same figure but the <code>contourf</code> plot is automatically at <code>z=0</code> level. I want to move the <code>contourf</code> plot to <code>z=-10</code> (or any value on z-axis) but I can't do it.</p>
  
  <p>I am sure it is easy but I can't find the answer in MATLAB help/Google.
  Any ideas?</p>
