Hi there,
I have created a simple page that shows a line chart using google api. The problem is, sometimes it showing on the browser, sometimes it doesn't. Can you help me figure out is there something wrong with my code.
<br />
<html><br />
<head><br />
<script type='text/javascript' src='https://www.google.com/jsapi'></script><br />
<script type='text/javascript'><br />
google.load('visualization','1',{packages:['corechart']});<br />
google.setOnLoadCallback(drawVisualization);<br />
function drawVisualization(){<br />
var data = new google.visualization.DataTable();<br />
data.addColumn('string','DateTime');<br />
data.addColumn('number','GBPUSD');<br />
data.addColumn('number','EURUSD');<br />
data.addRows(10);<br />
data.setValue(0,0,'22 Dec 07:00');<br />
data.setValue(0,1,'0.00000');<br />
data.setValue(0,2,'0.00000');<br />
data.setValue(1,0,'22 Dec 07:30');<br />
data.setValue(1,1,'-107.0');<br />
data.setValue(1,2,'-72.0');<br />
data.setValue(2,0,'22 Dec 08:00');<br />
data.setValue(2,1,'78.0');<br />
data.setValue(2,2,'71.0');<br />
data.setValue(3,0,'22 Dec 08:30');<br />
data.setValue(3,1,'126.0');<br />
data.setValue(3,2,'-77.0');<br />
data.setValue(4,0,'22 Dec 09:00');<br />
data.setValue(4,1,'197.0');<br />
data.setValue(4,2,'-42.0');<br />
data.setValue(5,0,'22 Dec 09:30');<br />
data.setValue(5,1,'288.0');<br />
data.setValue(5,2,'-29.0');<br />
data.setValue(6,0,'22 Dec 10:00');<br />
data.setValue(6,1,'256.0');<br />
data.setValue(6,2,'22.0');<br />
data.setValue(7,0,'22 Dec 10:30');<br />
data.setValue(7,1,'264.0');<br />
data.setValue(7,2,'-1.0');<br />
data.setValue(8,0,'22 Dec 11:00');<br />
data.setValue(8,1,'387.0');<br />
data.setValue(8,2,'8.0');<br />
data.setValue(9,0,'22 Dec 11:30');<br />
data.setValue(9,1,'362.0');<br />
data.setValue(9,2,'11.0');<br />
var options={<br />

var chart = new google.visualization.LineChart(document.getElementById('visualization'));<br />
chart.draw(data,options);<br />
}<br />
