Hello :)
I have 4d data (x y z coordinates and and V). I am hoping to represent the data similar to the slice function approach however I do not want the V values to be inerpolated for each square. I want each square to represent one of my data points (so x = 0, y=0, z=0 is a whole square not the inersection of squares as the slice function does). I could also potentially have a graph with circles for each data point or any other suggestions. I just need every data point to be visible.
[X,Y,Z] = meshgrid(0:4, 0:4, 0:3);
V = [0.95, 1.05, 0.87, 0.9, 0.66;
1.25,1.79, 18.1, 1.18, 1.22;
1.95, 6.27, 37.4, 6, 2.13;
3.06, 3.94, 11.4, 2.4, 1.8;
1.1, 1.3, 3.2, 1.8, 0.8];
V(:, :, 2) = [2.9, 2.7, 1.9, 3.1, 2.1;
1.1, 5.7, 18.5, 7.4, 0.6;
3, 10.9, 37.8, 14.5, 4.2;
2.6, 7.4, 9.4, 6.2, 3.8;
3, 2.2, 5.2, 3.8, 3];
V(:, :, 3) = [1.8, 3.2, 3, 3, 2.2;
3, 3, 14.9, 7.4, 1.8;
3.2, 10.7, 11.5, 23.9, 6.6;
2.2, 7.8, 9.8, 8.6, 3.8;
1.6, 1.8, 3.8, 3.8, 3];
V(:, :, 4) = [1.8, 2, 5, 4.4, 3.8;
2.2, 9.4, 8.8, 17.9, 5.8;
3.4, 20, 26.1, 20.1, 6.2;
4.4, 14.3, 6.6, 13.7, 6.6;
3.8, 3, 7.6, 3.4, 2.6];
zslice = [];
xslice = [0,1,2,3,4];
yslice = [];
figure
slice(X, Y, Z, V,xslice,yslice,zslice);
pbaspect([3 1 1])
colorbar
xlabel('X'); ylabel('Y'); zlabel('Z')

But you only have 4 values for Z direction

yes so i want 4 squares one for each value. I want each square to represent one of my data points not each square intersection

slice() just doesn't use last column and row for displaying colors
So i just copied values
[X,Y,Z] = meshgrid(0:4, 0:5, 0:4); % create bigger mesh
V = [0.95, 1.05, 0.87, 0.9, 0.66;
%%%%%%%
V = cat(1,V,V(end,:,:)); % one more row (last row copy)
V = cat(3,V,V(:,:,end)); % more data for 3d dimension (last matrix copy)
result:

thank you! am just wondering how would you do z slices instead ? I tried doing this - but doen't work... If you know, would be greatly appreciated :) x
[X,Y,Z] = meshgrid(0:5, 0:5, 0:3);
...
V = cat(1,V,V(end,:,:));
V = cat(1,V,V(:,end,:));

What about slice function?
