I don't think that you have to transpose the data using awk
, as each row already contains the data of a single particle.
So, based on the code from DragonHu, I have this:
To generate this plot, I also added lines to connect the points. Also, I used the special column number 0 which just gives the line number in the datafile, starting at 0.
Another trick: Using backslash \
, you can split a command to multiple lines. Here is the plot command I used:
plot "particle.dat" using 1:0 with points linetype 1 pointtype 7 pointsize 3 title "particle 1",\
"" u 1:0 notitle w l lt 1,\
"" u 2:0 w p lt 2 pt 7 ps 3 t "particle 2", \
"" u 2:0 notitle w l lt 2,\
"" u 3:0 w p lt 3 pt 7 ps 3 t "particle 3", \
"" u 3:0 notitle w l lt 3,\
"" u 4:0 w p lt 4 pt 7 ps 3 t "particle 4", \
"" u 4:0 notitle w l lt 4,\
"" u 5:0 w p lt 5 pt 7 ps 3 t "particle 5",\
"" u 5:0 notitle w l lt 5
Still, this is not yet the answer, as the question is to plot one set of points at a time. This can be achieved with the following code. It generates five single plots which I dumped into an animated gif figure:
set key center
set yrange[0:1]
set xrange[0:40]
set terminal gif size 600, 200 animate delay 100
set output "animated.gif"
do for [n=0:4] {
set title sprintf("Lineno. %d", n)
plot "particle.dat" every ::n::n using 1:(0) with points pointtype 7 pointsize 3 title "particle 1",\
"" every ::n::n u 2:(0) w p pt 7 ps 3 t "particle 2", \
"" every ::n::n u 3:(0) w p pt 7 ps 3 t "particle 3", \
"" every ::n::n u 4:(0) w p pt 7 ps 3 t "particle 4", \
"" every ::n::n u 5:(0) w p pt 7 ps 3 t "particle 5",\
}
unset output
If single images should be created, it is possible via
set terminal ongcairo
do for [n=0:4] {
set title sprintf("Lineno. %d", n)
set output sprintf("PictureNumber_%d",n)
plot ...
unset output
}
