for [intvar = start:end{:increment}] for [stringvar in "A B C D"]
例:
plot for [filename in "A.dat B.dat C.dat"] filename using 1:2 with lines plot for [basename in "A B C"] basename.".dat" using 1:2 with lines set for [i = 1:10] style line i lc rgb "blue" unset for [tag = 100:200] label tag
繰り返しの入れ子もサポートしています:
set for [i=1:9] for [j=1:9] label i*10+j sprintf("%d",i*10+j) at i,j
