Does anyone know of a way to visualize perf counter data similar to the
manner in which Performance Monitor displays perf counter data during
real-time monitoring. PM graphs each counter's value as the y-axis against
an x-axis that is shifting with time. I'd like to visualize the data
similarly, but with the x-axis static.

Back in the NT4 days (I forget which version of Excel) there was an add-in
"perfmon.xla" which allowed you to do this. But (as I expected) apparently
that add-in is obsolete ( no hits on searches of MS, MS Downloads, MSDN,
etc).
