Hi I have to do a scatter plot where each point in e.g. the xy-plane consist of determined value. My question is how do i plot a discrete amout of values where each of the values is related to a x, y-coordinate. I have seen reports with plots similar to the one presenten in the picture: scatter mesh.PNG
Hope to hear your input.
Best regards.

Use the surf (link) function and the view (link) function:
M = nan(50);
M(10:40, 5:30) = rand(31,26);
figure
surf(M)
view(0,90)
axis([1 size(M,1) 1 size(M,2)])
grid on

One simple option is to use pcolor:
>> M = randi([-3,6],5,7);
>> M([3,4,5,9,10,15]) = NaN;
>> pcolor(1:7,1:5,M)
