How to see most current metric data, most recent one and also in retrospective, but in one picture? Is that possible? Yes, it is.

I guess the simple radar in a plane or ship cockpit refreshes current data on a top of most recent and shows approaching "future". The SEDS control chart is similar and uses the border line to separate current data and most recent one. Plus it gives a historical base-line to show you what can be expected and for comparison.
I believe it is powerful way to visualize IT Systems Performance, so I made up a name for that chart: "IT-CHART".
(Not only because IT is my initials....)
I plan to add the pictures from this blog as additional slides to my CMG'09 workshop, which includes the R-script to build IT-CHART based on CSV input. (
