I agree it makes little sense to have points on the contour, except to show the principle of how they are generated. Perhaps (and the key implies that was intended, although that's probably an accident) they should be omitted by default. But you also can't give e.g. a different linewidth to the contour and the 3d grid. You'll have to save the contours to a data block via "set table $contours", switch off contour generation, and then (re)plot the contours after making the pm3d plot via replot for [i=1:5] $contours index i us 1:2:(0) lc i lw 2 (assuming 5 contour lines and the base to be at z=0). Anyway if you want to see your original datapoints instead of the interpolated dgrid3d points, you have to add them on top of the pm3d surface and contours. I think the graph you envision is just a bit too complicated to be made by just one single plot command. ;-) Best, Karl
