Sorry, I meant to follow up on this yesterday. Thanks for your reply but I figured it out. I had the wrong type of horizontal axis applied so when I was returning an xField value it was actually drawing the chart off to the right somewhere.

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! > > > > Im using examples right out of Adobes guides and several other guides Ive > found online on how to use a series dataFunction.
