I agree your point that (1/0) is string read from datafile not a value=20
but after using ($3) it is converted into value and behave correctly.=20
But my problem is to get a mesh from single dataset with a hole in it.=20
What I mean to say is that if you make any value of Z in grided dataset=20
as undefined and try to use splot command on it to plot the mesh then=20
you won't get the one. what you get are only Isolines and not any=20
x-Isolines. That's the problem that gnuplot don't plot x-isolines if for=20
any (x,y) coordinate value of Z is undefined (which is required for=20
plotting hole).
