title: How to get a beautiful color scale on (semi-)logarithmic 3d plots on Matlab?
body: <p>After having <a href="https://stackoverflow.com/questions/433364/how-to-draw-semi-logarithmic-3d-plots-matlab">this question</a> answered through a link to <a href="http://www.mathworks.com/matlabcentral/newsreader/view_thread/239232" rel="nofollow noreferrer">an external site</a>, I realized that I solved a problem, just to get another one: On a logarithm scale the C=Z parameter of MESH and SURF functions don't work very well. All you get is a blue graph, without the usual color gradient, that you get by passing 3 parameters.</p>
  
  <p>How to revert that?</p>
