Hi,
I'm not sure what's going on there, but i'm using the following gnuplot line command inside a function. The plot comes out like a beauty but gretl pops an error message "Failed to parse gnuplot file".
By the way, can someone tell me how to break the following command into 2-3 lines (I tried with "\", "\\","/","//" with no success :(
 
gnuplot 5 4 --matrix=my_data --with-lines --suppress-fitted {set title 'Lorenz Curve'; set grid; set yrange [0:1]; set xrange [0:1]; set xlabel 'percentage of cumulated population'; set ylabel 'percentage of cumulated income'; show xlabel; show ylabel}

Best,
artur
