You can add the curve, but gnuplot may not be the right tool to compute 
the data to be used in that curve.  Not unless you're willing to jump 
through some hoops with 'set term table' and the 2D 'smooth freq' plot 
option.

Gnuplot has 2 different groups of methods for turning scattered data 
into organized ones: in 2D, you have 'smooth', in 3D, you have 'set 
dgrid3d' mode.  Your task falls into the gap between those, which makes 
it tricky to accomplish.
