Re: [Gnuplot-info] datafile separator

[Tamas H. <ho...@gm...>]

you can try to reformat the datafile to use ',' as field separator, rather
than \t. If you're working in linux, it's very easy to do with e.g. sed. you
can then visually check if your data is correct. It is a workaround, but it
should save you a lot of headaches.
