Re: [Gnuplot-info] Extract filename

[Ethan M. <eam...@gm...>]

Assuming that the subdirectories are not themselves named Datasomething,
I'd use something like

    chop(fullname) = fullname[ strstrt(fullname,"Data") : * ]

    plot for [FileName in FileList] FileName u 1:2 w l title chop(FileName)
