It's unclear how you arrived at the data file you sent --- but it seems 
you ran off in exactly the wrong direction here.  You actually have a 
regular mesh of points, but the data file *hides* that structure as good 
as it possibly can.  If you wanted contours, you shouldn't do that.

On top of that, the z values in that file are all either 2, 5, 6 or your
"trademark" (1/0)-in-a-datafile.  That won't give you meaningful contour
lines.

If nothing else helps, consider 'set dgrid3d'.
