Hi
I am trying to add the tool tip with mouse over event. Any help will
be highly appreciated. This is what i tried so far:
<script type="text/javascript">
google.load("visualization", "1", {packages:["piechart"]});
google.setOnLoadCallback(drawVisualization);
function drawVisualization() {
var data = new google.visualization.DataTable();
data.addColumn('string', 'Stars');
data.addColumn('number', 'Percentage');
data.addRows(5);
data.setValue(0, 0, '1 star');
data.setValue(0, 1,12.96);
data.setValue(1, 0, '2 stars');
data.setValue(1, 1,16.67 );
data.setValue(2, 0, '3 stars');
data.setValue(2, 1, 22.22);
data.setValue(3, 0, '4 stars');
data.setValue(3, 1,20.37);
data.setValue(4, 0, '5 stars');
data.setValue(4, 1,18.52);
new google.visualization.PieChart(document.getElementById
('userid21')).draw(data, null);
google.visualization.events.addListener(data, 'onmouseover',function
(e) {
visualization.setSelection([e]);
});
google.visualization.events.addListener(data,
'onmouseout',pieMouseOut);
function pieMouseOut(e) {
visualization.setSelection([]);
}
}
Thanks
