I want to create a graph using Highcharts plugin and the data should be parsed as an XML file.
The XML file data2.xml is,
<data>
<row><t>1347559200</t><v>2.1600000000e+01</v></row>
<row><t>1347562800</t><v>2.1504694630e+01</v></row>
<row><t>1347566400</t><v>2.1278633024e+01</v></row>
</data>
The HTML coding is,
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>line chart</title>
</head>
<body>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js" type="text/javascript"></script>
<script src="highcharts.js"></script>
<script src="exporting.js"></script>
<div id="container" style="min-width: 400px; height: 400px; margin: 0 auto"></div>
<script type="text/javascript">
$(document).ready(function(){
options = {
chart: {
renderTo: 'container',
type: 'spline'
},
title: {
text: 'Temperatures'
},
subtitle: {
text: 'An example of time data in Highcharts JS'
},
xAxis: {
type: 'datetime',
dateTimeLabelFormats: { // don't display the dummy year
month: '%e. %b',
year: '%b'
}
},
yAxis: {
title: {
text: 'T (°C)'
},
min: 0
},
tooltip: {
formatter: function() {
return '<b>'+ this.series.name +'</b><br/>'+
Highcharts.dateFormat('%e. %b', this.x) +': '+ this.y +' m';
}
},
series: [{
name: 'Temperature',
data: []
}]
}
$.ajax({
type: "GET",
url: "data2.xml",
dataType: "xml",
success: function(xml) {
var series = { data: []
};
$(xml).find("row").each(function()
{
var t = parseInt($(this).find("t").text())*1000
var v = parseFloat($(this).find("v").text())
series.data.push([t,v]);
});
options.series.push(series);
}
});
chart = new Highcharts.Chart(options);
});
</script>
</body>
</html>
If I execute this code It opens fine in Internet Explorer and displays the result as

When I open this file in Chrome it gives me the result as,

with the error message:
XMLHttpRequest cannot load file:///C:/data2.xml. Origin null is not allowed by Access- Control-Allow-Origin.
so that I used Tomcat server to run this. Though it displays the same chart image without the mentioned error message.
How to overcome this?? How can I display the chart in Google Chrome by fetching data from xml file by solving this issue??
I got this working out..
I just run this code by using Apache/Tomcat..
I think the error I have made is that
1. I have to save this file in .jsp format.
2. add var to chart and options variable.
3. Use this
chart = new Highcharts.Chart(options);inside the success function.
