It's not quite clear what your 3D plot would have to do with 
frequencies.  It looks like you'll want to have a look at 'help pm3d', 
and eventually plot your data as

	set pm3d
	set view map
	splot 'Points.dat' matrix with lines

Another alternative would be

	set view map
	set contour base ; unset surface
	splot 'Points.dat' matrix with lines
