Hello, I want to capture the selected element in my timeline, but
chart.getSelection () [0]. Returns undefined.
var container = document.getElementById('timeline');
chartTimeLine = new google.visualization.Timeline(container);
dataTimeLine = new google.visualization.DataTable();
dataTimeLine.addColumn({ type: 'string', id: 'President' });
dataTimeLine.addColumn({ type: 'date', id: 'Start' });
dataTimeLine.addColumn({ type: 'date', id: 'End' });
dataTimeLine.addRows([
[ 'Washington', new Date(1789, 3, 29), new Date(1797, 2, 3) ],
[ 'Jefferson', new Date(1801, 2, 3), new Date(1809, 2, 3) ]]);
chartTimeLine.draw(dataTimeLine);
google.visualization.events.addListener(chartTimeLine, 'select',
timeLineSelected);
function timeLineSelected(){
alert(chartTimeLine.getSelection()[0].row);
}
