To follow up -the error relates to trying to add an addition line

actually a constant value of the dependent variable . I have tried y -

of the variables in the Gretl variable list,.. Each time error message
appears.
Brian, if you want to add a horizontal line, just enter the
numerical value into the formula box, e.g.
12.8
Basically the only other thing you can do in that box is type a
formula that references "x" (a hard-wired "x", meaning the x-axis),
as in
sin(x)
"y" or any other identifiers are unknown to gnuplot and will cause
an error.
