when using 'dgrid3d' the z values in the plot are computed as weighted
averages
or spline interpolation of scattered points. the usage of 'dgrid3d' makes
sense
for non-grid data.
you have grid data, so the only thing you need to do is to seperate the
datablocks
(representing y-isolines) with an empty line in the datafile, i.e. a blank
line between
each x=-20 and x=-6.
then 'unset dgrid3d' and 'splot' again.
