[Gnuplot-info] automatic iteration plot - folder name

[Nunzio L. <nun...@gm...>]

Hi all,

I want to plot some files with the same name located in some progressively
number folders (i.e.: 1, 2, 3, 4 ...) all at the same path level. So,
starting from the parent directory I do a

plot for[i=1:4]  i."/namefile" u 1:3 w linespoints

but then I get:

        internal error : STRING operator applied to non-STRING type

Is there a way to solve this? It is a bit strange, cause if I have some
progressively numbered files, instead:  namefile1, namfile2, namfile3, and
so forth, I can do - from the directory where files are:

plot for[i=1:3] "namefile".i u 1:3 w linesp

and get the result I want. Do you have any idea?

Thanks,

N.
