I need help with the plotting 3D surface.

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!

Data=[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];

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)

Thank you very much

Can you draw a finer mesh?

Can you draw a finer mesh?

It only makes sense if you supply more points.

Yes, thank you so much!
