Unfortunately, there's something I'm not understanding about pm3d:

gnuplot> splot "socks.dat" using 1:3:4 with pm3d
Warning: Single isoline (scan) is not enough for a pm3d plot.
Hint: Missing blank lines in the data file? See 'help pm3d' and
FAQ.

socks.dat is a file with several hundred thousand rows, four columns (column 2 is not used), and no breaks between rows.

... which means it doesn't describe any surface, so pm3d can't plot it
as a coloured surface. Looks like what you really want is a plot of coloured points, i.e.:

set view map
splot 'data' u 1:2:(0.0):3 with points palette

Either that, or you should insert the missing breaks into the data file.

That did the trick, thanks! I guess the third coordinate of 0.0 just basically push everything up against a 2D plane...excellent.

In my case, I was missing only "with points palette".
