Logically, no 4-D plot can be made sensible to us (unfortunately, we are stuck to see and understand 3-D world, only). So even if you could plot it somehow, understanding it will be quite tricky. Yet, fortunately this time, we can imagine n-D world theoretically (with n = 0 to inf).
Now, suppose your data set is something like D(x,y,z,T). At each point of (x,y,z) space, there is a (T) value that changes the behavior. So you want to visualize the (x,y,z) space at a given (T). Thus, the answer is (fix one coordinate, and change the other 3). The rest is how to do it.
When I needed it, I used to fix z-coordinate and plot (x,y) horizontally, with (T) in the vertical axis, as in the example below:
clc
clear
close all
for x=1:20;
for y=1:20;
for z=1:20
for T=1:20
D(x,y,z,T)=sin((T.*x.*z)*0.1);
end
end
end
end
[nio, njo, nko, nTo]=size(D);
surfl(D(:,:,1));
for k=1:nTo;
surfl(D(:,:,k))
xlabel(' X - Axis');
ylabel(' Y - Axis');
zlabel(' T - Axis');
title({' Z is fixed at: ' k })
pause (0.1);
CF(k)=getframe;
end
figure;
movie(CF);
Please modify it to your own convenience, this is NOT the code you exactly need, but the method is, I think.
