Hello, I've got a small problem with gnuplot. When I generate a scatter plot and try to include different fitted lines, gretl/gnuplot gives me an error after the attempt to remove the loess-curve again. It only happens with the loess-curve option. I've got no problems with other curves. The output is: 3.59261632 7.442232468 ^ "/home/artur/.gretl/gpttmp.n8NhWU", line 259: invalid command Best wishes, Artur
