Hi everyone, can anyone help me plot such colored cube graph? I have some experimental data which are 4 dimensional (x,y,z,f). Similarly to the example, I wish the color depends on the f, which is the 4th dimension.
Really! Thanks you very much!

Hi, did you figure out how to plot this kind of graph? I meet the same problem and I'm wondering can you share the solution? It's really appreciated!

It depends on how the data is....how is your data?

For an explanation of the following code, look at Multifaceted Patches. The individual colors you put have to map to the volume function in some manner (not done here). Hope it helps.
vert = [0 0 0;1 0 0;1 1 0;0 1 0;0 0 1;1 0 1;1 1 1;0 1 1];
vert = 2*pi*vert;
fac = [1 2 6 5;2 3 7 6;3 4 8 7;4 1 5 8;1 2 3 4;5 6 7 8];
C = rand(8,3);
% C = hsv(8);
patch('Vertices',vert,'Faces',fac,'FaceVertexCData',C,'FaceColor','interp')
view(3)

colorbar

I had the same question. I found that by using the slice function twice and setting the slices at the minimum and maximum extents of my domain in x, y, z that I was able to generate a 3D color contour figure like that.
figure
hold on
slice(data.X,data.Y,data.Z,data.U,min(min(min(data.X))),min(min(min(data.Y))),min(min(min(data.Z))))
slice(data.X,data.Y,data.Z,data.U,max(max(max(data.X))),max(max(max(data.Y))),max(max(max(data.Z))))
view(3);
grid on;
colormap(jet(64));
colorbar('vertical');
shading interp;
hold off
axis equal
