Normally, the way to pass parameters to the item renderer is through its "data" property. So just make sure that your data provider contains whatever information you need to set the item renderer position.

First question is whether I can pass actual parameters to a callback in the first place? This is what I need to do: <mx:ColumnSeries id="salesSeries" yField="sales" > </mx:ColumnSeries> <mx:LineSeries id="percSeries" yField="percent" lineSegmentRenderer ="PercentLineRen derer("orig callback params", "new callback params")"> </mx:LineSeries Conventionally of course the lineSegmentRenderer gets no params as a callback. But in this instance I need to manipulate the position of the "percent" line series lines through the renderer based on "sales" series data so that the lines are positioned exactly over the columns of the "sales" series". I have code in the renderer that positions the lines, but different underlying data for the column series (2 side by side cols for each data point), changes the width and horizontal position of the columns and then the "percent" line fragments above no longer line up. If I could get the "sales" series info to the "percent series "renderer" I think I stand a chance of coding "interacting series" A big thank you in advance, Mic.
