I think there is one scenario where the measuring points and the points
from dgrid3d are the same points. If the measuring points (X-coordinates
and Y-coordinates) are like a monotone grid and no option like splines
is used at the dgrid3d command.

So at my example the plot with and without

set dgrid3d 5,5
set contour base

is the same. But without the dgrid3d I must insert blank lines between
every data block.
