How to

Dear all,

 

I'm trying to create a 2D plot of a 3D map using the contour fucntion.

The following code is already a valid basis, i.e. it creates the plot below:

  x = -2:0.2:2;
  y = -2:0.2:3;
  [X,Y] = meshgrid(x,y);
  Z = X.*exp(-X.^2-Y.^2);
  contour(X,Y,Z);

 

What I would like to have instead, is lines instead of surfaces and labels showing the value of each line (e.g. like the image below).

 

 

Is there a way to realize this in Compose?

 

Thank you in advance!
Christian
