How can I create a 4D plot using 4 different Vectors.

Hey guys,

My problem is plotting 4 different vectors ( each having 7000 samples). I have tried using plot3, but it does not provide me the required results.

clc; clear; load Sign1.mat; sign=Sign1';

t=sign(1:7000,1);

xy=sign(1:7000,2:3);

z=sign(1:7000,4); figure; plot(t,z); figure; plot3(t,xy,z); rotate3d on;

Here, Sign1.mat is a file which contains all the four vectors in the form of a matrix (7000*4). The objective is to view these vectors in 4D ( like a 4D figure).

I would appreciate it if anyone could help me with this problem.

I would be exceedingly obliged.

Thanks Arun

Hello Arun,

To visualize four-dimensional data in MATLAB, you can use a scatter plot where the color or size of the markers represents the fourth dimension. In MATLAB, you can achieve this using a scatter plot where the color or size of the markers represents the fourth dimension. Here's how you can modify your code to achieve a 4D-like visualization:

load Sign1.mat;
sign = Sign1';

% Extract the vectors
t = sign(1:7000, 1);
x = sign(1:7000, 2);
y = sign(1:7000, 3);
z = sign(1:7000, 4);

% Create a 3D scatter plot with color representing the fourth dimension
figure;
scatter3(t, x, y, 36, z, 'filled');
xlabel('t');
ylabel('x');
zlabel('y');
title('4D Visualization using Color');
colorbar; % Add a color bar to indicate the scale for the fourth dimension
rotate3d on;

This approach will give you a visualization where the fourth dimension is represented by varying colors, providing a pseudo-4D view of your data.
