MATLAB: Add label to a contour when when multiples plots

Question

Hello saviors,

so, I'm creating three contour from trhee matrix array on a single plot using hold on:

 hold on
 contour (muvec, muvec, spaln(:,:,1))
 contour (muvec, muvec, spaln(:,:,2))
 contour (muvec, muvec, spaln(:,:,3))
 hold off

What I want is to label each contour with 1, 2, 3 for each matrix, so I can know which contour represent wich matrix array.

thank you all

Answer 1

They appear to be plotted on the same set of coordinate matrices. One option is to use different line colours (and other variations) for each contour plot. You might also consider contour3, that will allow you to separate them vertically.
