I currently have a plot where there are three dimensions plotted and a fourth variable is represented by color. Regions with the same color represent areas where the fourth variable is close to equal. I would like to represent each of the regions with the same color (in the image attached) as volumetric surfaces (or interpolated as curves in some meaningful way).
I have tried a variety of approaches, including contour3 plots, etc, but I am looking for suggestions on how I can further improve the visualization of clusters in this 3-dimensional plot of points with the same color.
Additionally, side question, I have a 5-dimensional system where all 5 of the dimensions are mostly uncorrelated. What are some techniques through which I can visualize this system in a 3-dimensional space? One method that I tried is training a MATLAB fitnet neural network that can approximate the fourth dimension based on the other values.
