Can you try removing some of those series to isolate the problem? Also, can we see the console output from the trace statements in seriesDataFunction?
Maybe the values are out of bounds? Some sample data would be useful too if that's possible. 2009/6/12 Jake Churchill <[email protected]>: > > > Charting people, please help! > > > > I’m using examples right out of Adobe’s guides and several other guides I’ve > found online on how to use a series dataFunction.
