The key to this puzzle is in your data file.  Using dgrid3d would force 
it to be geometrically rectangular.  So you don't want to use it.

That means you have to achieve grid structure yourself, by preparing the 
data accordingly.  See "help splot datafile" for what that means. 
You'll probably have to repeat data points or add dummy ones (with 
undefined or out-of-range z values that you can filter away).
