Yes, that "is" syntax was the ticket - thanks, Matt. To paraphrase Bill
Clinton, I now know what the meaning of is is.
I did have to do it slightly differently, to avoid a "no return value"
error - storing the return string in a variable outside the if statement.
Here's how it looks:
private function buildDataTip(e:HitData):String
{
var returnItem:String;
if (e.element is ColumnSeries)
{
var col:ColumnSeries = ColumnSeries(e.element);
returnItem = "<b>"+col.name+":</b><br>"+ e.item[col.yField];
}
else if (e.element is LineSeries)
{
var line:LineSeries = LineSeries(e.element);
returnItem = "<b>"+line.name+":</b><br>"+ e.item[line.yField];
}
return returnItem;
}
