3.10 iteration
The ‘plot‘, ‘splot‘, ‘set‘ and unset commands may optionally contain an iteration clause. This has the effect of executing the basic command multiple times, each time re-evaluating any expressions that make use of the iteration control variable. Two forms of iteration clause are currently supported:
for [intvar = start:end{:increment}] for [stringvar in "A B C D"] |
Examples:
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 |
See additional documentation for iteration.
