That was the wrong idea.  You should just have put the 'p' (and 's') 
column in the same file as x, y and z.  gnuplot can pick any three or 
four columns out of a multi-column data file and use them as plot 
coordinates.

Read 'help datafile', 'help pm3d' and 'help splot using' thoroughly, and 
you should be able to figure out how to get the plot you need.  Pay 
particular attention to the concept of grid data.
