Reference lines

[#1]

Hi

I'm making graphs for every column of my data sheet using a for loop and I have 2 rows in my table that have the tolerance for every parameter (=column). 

I'd like to add those tolerances as reference lines like this : {Add Ref Line( {}, "Solid", "Gray", "", 1, 0.25 )}    but I don't know how to refer to my tolerance lines in those {}.

Any help would be appreciated
