Hi vinodn,
You can achieve this by using the series colorFunction callback. Here is an example, based on the demo Pie Series:
<!DOCTYPE html>
<html lang="en">
<head>
<link rel="stylesheet" href="../../../jqwidgets/styles/jqx.base.css" type="text/css" />
<script type="text/javascript" src="../../../scripts/jquery-1.11.1.min.js"></script>
<script type="text/javascript" src="../../../jqwidgets/jqxcore.js"></script>
<script type="text/javascript" src="../../../jqwidgets/jqxdraw.js"></script>
<script type="text/javascript" src="../../../jqwidgets/jqxchart.core.js"></script>
<script type="text/javascript" src="../../../jqwidgets/jqxdata.js"></script>
<script type="text/javascript">
$(document).ready(function () {
// prepare chart data as an array
var source =
{
datatype: "csv",
datafields: [
{ name: 'Browser' },
{ name: 'Share' }
],
url: '../sampledata/desktop_browsers_share_dec2011.txt'
};
var dataAdapter = new $.jqx.dataAdapter(source, { async: false, autoBind: true, loadError: function (xhr, status, error) { alert('Error loading "' + source.url + '" : ' + error); } });
// prepare jqxChart settings
var settings = {
title: "Desktop browsers share",
description: "(source: wikipedia.org)",
enableAnimations: true,
showLegend: false,
showBorderLine: true,
legendPosition: { left: 520, top: 140, width: 100, height: 100 },
padding: { left: 5, top: 5, right: 5, bottom: 5 },
titlePadding: { left: 0, top: 0, right: 0, bottom: 10 },
source: dataAdapter,
colorScheme: 'scheme02',
seriesGroups:
[
{
type: 'pie',
showLabels: true,
series:
[
{
dataField: 'Share',
displayText: 'Browser',
labelRadius: 120,
initialAngle: 15,
radius: 170,
centerOffset: 0,
formatSettings: { sufix: '%', decimalPlaces: 1 },
colorFunction: function (value, itemIndex, serie, group) {
switch (dataAdapter.records[itemIndex].Browser) {
case 'Internet Explorer':
return '#6495ED';
case 'Firefox':
return '#D2691E';
case 'Chrome':
return '#FFD700';
case 'Safari':
return '#696969';
case 'Opera':
return '#B22222';
default:
return '#DCDCDC';
}
}
}
]
}
]
};
// setup the chart
$('#chartContainer').jqxChart(settings);
});
</script>
</head>
<body class='default'>
<div id='chartContainer' style="width: 850px; height: 500px;">
</div>
</body>
</html>
