(Can you please use different colors next time?) Sorry, I'm a bit rusty with gnuplot. Color charts are updated with the same url. On the last one, I was trying to plot same CPU type with same color but different line weight for each kernel, plot "data" using 1:2 title "2P Xeon 3.4 GHz - vanilla" with linespoints lt 1 lw 10, \ "data" using 1:3 title "2P Xeon 3.4 GHz - lockless" with linespoints lt 1 lw 1 gnuplot gives me the same color on both plotted lines, but the line weight argument doesn't have any effect. I looked for examples everywhere on the web with no avail. I must be missing some argument somewhere that I can't figure out right now :-(
