i'm making a random dataset and interpolating a surface with tri_surf.

when i use regular griding (don't include an X and Y in the statement)
the range is 0 to 1 (because i'm using RANDOMU) which is what i want it to be.

however, when i add irregular griding, via a RANDOMU array to make my X and Y grid the Z value shoots up to a range of 0 to 10 or 15...it changes every time i run the program

any ideas on how to get a 0 to 1 range in Z and use irregular griding?
