I need to handle the onclick event over a Gauge. I don't have found an
example for register events over Gauges on the Google Chart
documentation.
I have tried the following:
<html>
<head>
<script type="text/javascript" src="https://www.google.com/
jsapi"></script>
<script type="text/javascript">
google.load("visualization", "1", {packages:
["corechart","gauge"]});
google.setOnLoadCallback(drawChart);
function drawChart() {
var data = new google.visualization.DataTable();
data.addColumn('string', 'LABEL');
data.addColumn('number', 'TOTAL');
data.addRows(1);
data.setValue(0, 0, 'Speed');
data.setValue(0, 1, 240);
var gaugeOptions = {min: 0, max: 280, yellowFrom: 200,
yellowTo: 250, title: 'Company Performance', redFrom: 250, redTo: 280,
minorTicks: 5};
var gauge = new
google.visualization.Gauge(document.getElementById('gauge_div'));
gauge.draw(data, gaugeOptions);
google.visualization.events.addListener(gauge,
'select', function() {
alert("Here");
});
}
</script>
</head>
<body>
<div id="gauge_div"></div>
</body>
</html>
Also I have tried to add onclick event with JQuery to div "gauge_div"
but it only works if I make click on the border of div, not over the
gauge.
How can I do this?
