Sar2gp converts files generated by 'Sar' from Sysstat into Gnuplot format, and then generates the graphic. User can select which values wants to be plotted. Sar2gpGUI is a graphical user interface that can deal with all Sar2gp options.
sarface is a user-interface to the sysstat/sar database which inputs data from sar and plots to a live X11 graph via gnuplot. It mimics the cmd-line options from sar but can cross-plot any two or more stats and apply simple mathematical functions them.
