Displaying a 3D mesh cell color value by placing the pointer over it

Dear all.
I have been working with Gnuplot 3D-mesh graphs for a couple of years now and and have created complex graphs. I use four dimensions: 3 data columns for the 3D-plot and 1 data column for surface cell coloring. I use gnuplot library within C++ coding.
I have seen that other folks display a surface cell value within the 3D mesh by placing the pointer over the cell. The fourth dimension value (color value) gets displayed.
I would very much appreciate if anybody could let me know how to do it. I have looked for it without much success.
