This example gives you each 3 points in a different color:

reset
set encoding utf8
set grid
set xrange [0:10]
set yrange [0:10]
$data << EOD
1   4   6   5   9   2   7   6
2   5   7   3   2   7   2   8
3   7   3   9   3   2   1   0
4   7   5   2   8   1   2   8
5   5   2   9   4   2   6   1
6   7   3   9   3   2   1   0
7   5   7   3   2   7   2   8
8   7   3   9   3   2   1   0
9   7   5   2   8   1   2   8
EOD
set pointsize 5
plot $data every ::0::2 u 1:2 w p pt 7 lc 'red', $data every ::3::5 u
1:2 w p pt 7 lc 'blue', $data every ::6::9 u 1:2 w p pt 7 lc 'green'


"every" seams to be one solution.
