How to plot a 4D plot (X , Y , Z and Intensity) ??

I have like 4 Columns (X,Y,Z and Intensity). How can I plot a 4D plot??

-5.000000e-03 -5 -2 1808724575000000 -4.989990e-03 -5 -2 1771033352400000 -4.979980e-03 -5 -2 1726418476100000 -4.969970e-03 -5 -2 1675286124200000 -4.959960e-03 -5 -2 1618110215600000 -4.949950e-03 -5 -2 1555428767400000 -4.939940e-03 -5 -2 1487838612700000 -4.929930e-03 -5 -2 1415988772600000 -4.919920e-03 -5 -2 1340576095300000

Hi,

To plot a 4D plot where you have columns for X, Y, Z, and Intensity, you can use the “scatter3” function, which allows you to visualize data in three dimensions and use the fourth dimension to control the colour or size of the markers. Refer to an example implementation for a better understanding:

% Define your data
X = [-5.000000e-03, -4.989990e-03, -4.979980e-03, -4.969970e-03, -4.959960e-03, -4.949950e-03, -4.939940e-03, -4.929930e-03, -4.919920e-03];
Y = [-5, -5, -5, -5, -5, -5, -5, -5, -5];
Z = [-2, -2, -2, -2, -2, -2, -2, -2, -2];
Intensity = [1808724575000000, 1771033352400000, 1726418476100000, 1675286124200000, 1618110215600000, 1555428767400000, 1487838612700000, 1415988772600000, 1340576095300000];

% Create a 3D scatter plot
scatter3(X, Y, Z, 36, Intensity, 'filled');

% Add labels and title
xlabel('X-axis');
ylabel('Y-axis');
zlabel('Z-axis');
title('4D Plot using scatter3');

% Add a colorbar to show the intensity scale
colorbar;
colormap jet; % You can change the colormap as needed

For more information on the “scatter3” function refer to the below documentation:
