Isosurface with discrete data 4-dimension data? how to plot surface passing through a series of points?

Hi ALL,

I have a series of data F as function of X,Y and Z.

F,X,Y and Z are all 1-column vectors

I wish to plot them in a 3D space and use color as "4th dimension", basically the color of the marker/line/surface should be linked to the data in F

I produced a scatter3 plot but this is very confusing to read.

The values F are (more or less) such that 2 < F < 3.

Ideally I wish to be able to plot a surface passing through all the point where 2 < F < 2.2 with a color (blue) then another surface passing through all the point where 2.2 < F < 2.4 and so on up to the surface passing trough through all the point where 2.8 < F < 3 with red color

Any idea on how I can I do that?

Thanks in advance for your help
