You say your data is already on a grid? For those points on the grid
that do not have defined z values, set the values to something big
and use the MAX_VALUE keyword of the SURFACE routine to plot your
data. This is the IDL version 3.6 way. version 4 has some new
considerations of NaN's which may also provide a solution.
