clickable column chart

Flow

HI,
Is there a way to make a visualization add-on column chart clickable?

chart.addListener(new ColumnChart.SelectionListener() {
public void selectionChanged(List selectedItems) {
int size = selectedItems.size();
}
});

Selection event seem to fire alright yet you cannot get the selected item (selectedItems is null).

Thanks!

If not - which add-on (column chart ) does?
