I have been seeing the same behavior with the Gauge chart type. I am using
it for a dashboard and it is updated frequently from the server via a
Socket.IO broadcast to all currently connected employees. I don't believe
this was happening before the most recent release so it may be a regression.
Here is my usage code (I scrubbed it to be more generic, so it may not be
perfectly syntactically correct but I was careful nonetheless):
google.load('visualization', '1', {packages:['gauge']});
function Gauge() {
this.gauge = new
google.visualization.Gauge(document.getElementById('m'));
this.gaugeOptions = {
min: 0,
max: 200000,
greenFrom: 0,
greenTo: 100000,
yellowFrom: 100000,
yellowTo: 180000,
redFrom: 180000,
redTo: 200000,
animation: {
duration: 1000,
easing: 'out'
},
majorTicks: ["0","","100,000","","200,000"],
minorTicks: 5
};
this.data = google.visualization.arrayToDataTable([
['c1', 'c2', 'c3'],
[0, 0, 0],
]);
this.gauge.draw(this.mqData, this.gaugeOptions);
}
Gauge.prototype.draw = function() {
this.gauge.draw(this.mqData, this.gaugeOptions);
}
// in main code
gauge = new Gauge();
socket.on('some_event', function(data){ // This is emitted about once
a second. After about an hour the Chrome tab crashes
gauge.data.setCell(0, 0, parseInt(data.c1, 10));
gauge.data.setCell(0, 1, parseInt(data.c2, 10));
gauge.data.setCell(0, 2, parseInt(data.c3, 10));
gauge.draw();
});
