NB: This applies only to the development version (4.7) ------------------------------------------------------ Suppose you have a parametric function of dummy variable A X = fx(A) Y = fy(A) To plot this using the '+' syntax you would first specify the expected range on x and y and then sample the functions of A. For example: fx(A) = sin(0.2 * A) fy(A) = 3 * cos(A) set xrange [-3:3] set yrange [-3:3] plot sample [A=0:20] '+' using (fx($1)) : (fy($1)) with lines The '+' indicates a 1-dimension sampling. The individual samples are indexed by $1. The plot generates x coordinates from fx($1) and y coordinates from fy($1). The paired x and y coordinates are connected by lines. You don't say what it is you might want to iterate over. Why don't you get this much working and then ask again. Ethan
