a small example (tested with the 'x11' terminal):
data.dat:
1 1
2 4
3 2
4 1
5 5
6 3
7 4
8 2
9 1
10 5
main.plt:
reset
set macro
set xrange [0:11]
set yrange [0:6]
i=1
n=5
load 'loop.plt'
loop.plt:
temp = "call 'plot.plt' 'data.dat' ".i." ".n
print temp
@temp
pause mouse keypress
if (MOUSE_KEY == 43) i=i+1
if (MOUSE_KEY == 45) i=(i>1?i-1:1)
print MOUSE_KEY
reread
plot.plt:
plot '< tail +$1 $0 | head -$2' with linespoints
start with loading 'main.plt' and use the '+' or '-' key when the
mouse pointer is in the plot window.
