gnuplot plot loop through axes

Question

While plotting in gnuplot, is there a way to loop through axes? Something like this:

var_axes="x1y1 x1y2" plot for [i=1:2] datafile using 1:2 axes word(var_axes,i)

It complains: "axes must be x1y1, x1y2, x2y1 or x2y2"

Answer 1

You can construct your plot command in a string variable, and then use eval to execute it:

var_axes="x1y1 x1y2"
cmd = "plot "
do for [i=1:2] {
   cmd = cmd . "datafile using 1:2 axes "   . word(var_axes,i)
   if (i < 2) {
     cmd = cmd . ", "
   }
}
eval cmd
