Various cases can be handled with suitable command-line options. For instance, Grace uses the "-nxy" switch to indicate that following file is organised in several data columns, the first one being the common abcissa and the rest the curves to plot. Anyway, a bug tracker is not the best place to discuss that. I'll try to subscribe to some labplot mailing list and eventually make there my humble contribution to the discussion. Orestes.
