[Gretl-users] loop, string substitution and varname from list

Hello everyone, I am constructing a set of xy plots in a loop, using a predefined list of variables for the plots. I'd like the names of the plots to include the variables names. Here is a MWE, including some comments on what I tried and did not work: ------------------- #Loop through list of vars and create xy plots nulldata 100 setobs 1 1 --cross-section x_1 = uniform() x_2 = uniform() y_1 = uniform() y_2 = uniform() list xs = x* list ys = y* loop for (i=1; i<=nelem(xs); i++) $i <- gnuplot xs[i] ys[i] #works #printf "%s", varname(xs[i]) #works not -- error msg not of help #string name = varname(xs[i]) #works not -- error msg indicates series ID needed #string name = "@xs[i]" #works not either -- error msg not of help string name = "name_$i" #works @name <- gnuplot xs[i] ys[i] #works endloop ------------------- Any idea how I can make this work? Kind Regards, Frederik
