I am graphing CPU load average over time (5s intervals). Traditionally this is done as a solid filled area graph rather than a single floating line, for example …
It seems a very simple request, but I’ve not been able to find the solution.
My one remaining avenue is to subclass the default renderer .. but I keep thinking there has to be something simpler.
Your clues & other pointers would be most welcome.

You are probably looking for an
org.jfree.chart.renderer.AreaRenderer. Several examles are shown in the java-web-start sample demo under Area Charts. Alternatively, anXYBarRenderermakes a nice histogram.
