Hi everyone,
I need help with the plotting 3D surface.
I have a matrix as follows:
Data1=
[6 100 41.36
6 150 39.26
6 200 37.63
7 100 54.22
7 150 52.26
7 200 50.11
8 100 61.18
8 150 59.38
8 200 55.33];
I would like to show the 3D like the attached figure.
where P corresponds to column 1 of the matrix;
L corresponds to column 2 of the matrix;
and Rz corresponds to column 3 of the matrix;
Thank you so much!

8 200 55.33];
x = Data(:,1);
y = Data(:,2);
z = Data(:,3);
xi = unique(x);
yi = unique(y);
[X,Y] = meshgrid(xi,yi);
Z = reshape(z,size(X));
%adjust color accordingly
C(:,:,1)=57*ones(size(Z))/255;
C(:,:,2)=255*ones(size(Z))/255;
C(:,:,3)=20*ones(size(Z))/255;
surf(X,Y,Z,C)

Can you draw a finer mesh?
It only makes sense if you supply more points.
