Is there any reason why it can not take a list of numbers ?

[<pl...@pi...>]

Hi,


the iteration in gnupllot is an excellent feature but can not take an 
irregular sequence of numerical variables.

it's either a straight integer series or a list of _string_ variables.


Is there any reason why it can not take a list of numbers ?

eg. if I want vertical arrows  at  x= 11,13,17  it does not seem 
possible with the existing iteration.


help tells me:

Two forms of iteration clause are currently supported:

        for [intvar = start:end{:increment}]
        for [stringvar in "A B C D"]




why not for [intvar = 11,13,17]   ?


is there a trick to a string value in set arrow ?

set     for [stringvar in "11 13 17"]  arrow  from  ???, 0 to ???,1


Is there a problem to specify intvar with a list of values instead of a 
regular series?

Thanks, Peter.
