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. The gnuplot command I use: splot '-' using 1:2:3:4 with lines lc rgb 'black' Regards Javero
