Book1.xlsx

Respected sir,

I am attaching an excel file here.

I want a plot between columns' values F, G, H and I for 216 values in such a manner that values of l1, l2 and l3 should be along X, Y and Z axes and plot of values of Lz in between.

Here, every value of l1, l2 and l3 leads to the value of the corresponding value of Lz and the range of each one of l1, l2 and l3 is between 800 to 1200.

Kindly let me know how to draw this plot.

Thanks in advance.

Anshul

Have a look on slice.

T = readtable('Book1.xlsx') ;
l1 = T.l1 ; 
l2 = T.l2 ;
l3 = T.l3 ;
Lz = T.Lz ;
nx = length(unique(l1)) ; 
ny = length(unique(l2)) ; 
nz = length(unique(l3)) ; 
X = reshape(l1,nx,ny,nz) ; 
Y = reshape(l2,nx,ny,nz) ; 
Z = reshape(l3,nx,ny,nz) ; 
C = reshape(Lz,nx,ny,nz) ;
figure
hold on
for i = 1:nz
    surf(X(:,:,i),Y(:,:,i),Z(:,:,i),C(:,:,i))
end
