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 plot iteration (p. [*]).
