Assuming that you have assigned an id to each series
("baseline","2009-8"), you could use something like this:
private function dtFunction( o:HitData ):String
{
var index:int = ( LineSeries( o.element ).id == "baseline" ) ? 0 :
1;
var s:String = "<b>Book rate:</b> " + o.item.session[ index
].bookrate;
return s;
}
