I don't believe you can pass params. An alternative would be to have
your lineRenderer query upwards for the data. I do something similar
and added the following code in my updateDisplayList();
(I don't know how important the initial "LineSeries" check is)
override protected function updateDisplayList(wd:Number,ht:Number) {
var lc:LineChart;
if (parent is UIComponent) {
var myParent:String = String(UIComponent(parent).className);
if (myParent !="LineSeries")
return;
var ls:LineSeries = parent as LineSeries;
lc = ls.owner as LineChart;
var salesInfo:Number = lc.getSalesInfo(); // talk to lineChart here
