How to make a 4D graph
13 views (last 30 days)
I am extremely new to Matlab (downloaded approximately 10 minutes ago new). I have been looking online for some templates, but nothing seems to be quite what I am looking for. I have four data points: length (x), width (z), height (y), and CO2 concentration (c). I want the fourth data point, the CO2 concentration, however, represented by a color depending on the concentration. Say, a darker color hue for lower concentrations and a lighter color hue for higher concentrations. Is there a way I can do this where I can just insert an excel file? I just have no idea where to start or where to look. Any help is much appreciated!

Technically, you cannot visualize 4d plot in MATLAB. That being said, you can 3d slices in matlab using the slice command http://www.mathworks.com/help/matlab/ref/slice.html. However, you might want to choose a syntax which allows colors in the code.
To load an excel file into MATLAB, use xlsread http://www.mathworks.com/help/matlab/ref/xlsread.html.
You will have to write your code for loading and plotting. Maybe, there are user submitted code http://www.mathworks.com/matlabcentral/fileexchange/ for this routine.
