You may find these examples from the on-line demo set to be useful:

1) Example of generating and contouring a surface from the distribution
of non-gridded 2D data (in your case the Z coordinate of each [x,y] is the 
number of occurances)

  http://gnuplot.sourceforge.net/demo_svg_5.2/scatter.html

2) Align 2D and 3D distributions as in the URL you point to
