Hi Bus,
What sort of data are you trying to visualize? Without a specific idea, a few general recommendations for you:
- For better visualization of functions of 4 variables, I recommend taking a look at sliceomatic
- For visualizing the fourth dimension specifically with color, you can change the size of the markers and/or colors of each point with scatter3. For example, if I replaced your last line with:
markerSize = 100;
scatter3(x,y,z,markerSize,c,'filled')
colorbar
then the plot will now have data points whose color is the linear mapping of the values in C to the colors in the current colormap- the way you had it before was altering the size instead of color. If you would prefer to specify a RBG color value instead, you could also give it a 3 column matrix with the number of rows in C equal to the length of X, Y, and Z. This way, each row could then specify an RGB color value for each marker. This is especially handy if you want to change each marker separately (by size and/or color). You could also change the RGB value to be proportional to the value of c (ex: c/max(c)) as well.
Hope this helps!
