Hello.
I'm developing a JRuby-powered JFreeChart server, that gets POST data and definitions for charts and returns a Base64-encoded PNG containing the chart. So far, so good but I also need to draw "markers" to serve as visual cues for threshold values on certain graphs. For XY plots, addRangeMarker (I can make for example Y from 1 to 3 have a yellow background) is my friend, but for SpiderWebPlots there is no such easy way to do it, as I can see it.
Can I use drawRadarPoly to get the same effect? If so, how can I create an adequate PlotRenderingInfo structure?
Thanks for any feedback!
