My feeling is that the graphics in the Performance Toolkit satisfy the interests of the original author. If you want more, you need to go to a real graphics package. GDDM comes to mind, but so do some vague unpleasant memories, but I do think that dual scales (a left hand scale for CPU and a right hand scale for I/O or TrivResp) is possible. Personally, I extract the data from PTK and use GnuPlot on my windows workstation to design a plot. When I am satisfied, I transfer the control information and updated data to a Linux system for batch creation of graphics that can be emailed to managers or displayed on a web page. Something that my Linux associates are urging me to look at is the RRDTOOL for the accumulation and display of this time-based performance data. The BigBrother monitoring package does a interesting job of presenting some data (examples available on request).
