You told ListPlot to PlotJoined and it did so, based on the list you provided. In order to get what you want, as opposed to what you've asked for, you'll need to partition your list, then use something like MultipleListPlot[] Needs["Graphics`"] newlst = {Take[lst, 5], Take[lst, -5]}; MultipleListPlot[newlst] Regards, Dave.
