Re: [Gnuplot-info] set table

[ivana r. <iva...@mf...>]

Hi Patrick,

even if you force two columns, e.g. 'plot $DATA u 1:2'?

It seems to me that gnuplot take the table $DATA as it has only one
numerical column. Is it possible that there are some special chars left?

If so, it should help to get table via 'plot file using
($1/1000):($3+0)' instead as well.
