MATLAB: Difference between a contour map and surface map

3dcontourplot

What is the difference btwn a contour map and surface map?

I know that for both the lines are connecting the same quantity.

And we can have a colored-in contour map which then becomes

a surface map? So what is the difference?

Unless there is something in your question I have not understood, the contour plot is 2-D and the surface plot is 3-D. The information in both is the same. The surfc function actually plots both in the same figure.

You can use hold to overlay multiple plots on one set of axes. The following code demonstrates the concept using stem3 to plot the datasets.

% Random inputs
A = randn(20,3);
B = randn(20,3);
figure;
% Create a 3-D stem plot for dataset A
stem3( A(:,1) , A(:,2) , A(:,3) ,'blue')
hold on; % Activate hold
% Create a 3-D stem plot for dataset B
stem3( B(:,1) , B(:,2) , B(:,3) ,'red')
hold off %turn off hold
legend('A','B')
