The column of the selected item tells you what data series it comes from.
Incidentally, your selector code is prone to breaking: if the user
deselects a point, the #getSelection method will return an empty array, and
element 0 of an empty array doesn't exist. This is the safe way to handle
selections:
function selectHandler () {
var selection = chart.getSelection();
if (selection.length) {
var selectedItem = selection[0];
// do something with selected item
}
}
