[Suchada P. <coo...@ho...>]

 Hi
 
Is there anyone knows?, How to plot dashed line with gnuplot please? 
Now I use gnuplot 4.0, can this version plot dashed line?
 
Now, my setting like this
set terminal png medium
set output 'xxx'
set xlabel 'Time (minutes)'
set ylabel 'xxx'
set xtics 0, 5, 100
set ytics 0, 1, 5
set xrange [0:100]
set yrange [0:5]
set samples 10000
plot '/home/aa.dat' using 1:2 lw 3 title 'aa' with steps,'/home/bb.dat' using 1:3 lw 3 title 'bb' with steps,'/home/cc.dat' using 1:4 lw 3 title 'cc' with steps
 
thanks,
