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!
