Hi I need to show the temperature evolution of a lake in different depths through time. I have a matrix (Z) with dimensions: 1000x20 (temperatures observations x in different depths) so I have temperature data for 20 depths (with different intervals) for 1000 day and I want a graph like attached. I am sure I have a to use contourf, but I don't know how to use it for my case. Can anyone help me?

I do not know what your data are, so I can only guess.
I would use the surf (link) funciton to do the plot, then the appropriate view (link) to orient the plot correctly.
Example —
[X,Y] = ndgrid(0:0.1:20); % Create Data
Z = sin(pi*X/20) .* exp(-Y*0.2); % Create Data
figure
hs = surf(X, Y, Z);
set(hs, 'EdgeColor','none')
view(180, 90)
