<html><body bgcolor="#ffffff">I am actually using CentOS. I am looking for a program that, given data like X,Y1,Y2 X,Y1,Y2 X,Y1,Y2 X,Y1,Y2 ... (each row different) will plot a graph, actually two graphs, Y1:X and Y2:x, and maybe connect the Y1s and Y2s. Actually, simple plotting graphs. Can anyone suggest something? Really all it is is cpu vs. time, and memory vs. time <div></div> </body></html>
