    Hello vinoth,

    Here is an example, based on the demo Negative Values:

    <!DOCTYPE html>
<html lang="en">
<head>
    <title id='Description'>jqxChart Columns Series with Negative values</title>
    <link rel="stylesheet" href="../../jqwidgets/styles/jqx.base.css" type="text/css" />
    <script type="text/javascript" src="../../scripts/jquery-1.10.2.min.js"></script>
    <script type="text/javascript" src="../../jqwidgets/jqxcore.js"></script>
    <script type="text/javascript" src="../../jqwidgets/jqxdata.js"></script>
    <script type="text/javascript" src="../../jqwidgets/jqxchart.js"></script>
    <script type="text/javascript">
        $(document).ready(function () {
            // prepare the data
            var source =
            {
                datatype: "json",
                datafields: [
                    { name: 'month' },
                    { name: 'min' },
                    { name: 'max' },
                ],
                url: '../sampledata/weather_geneva.txt'
            };

            var dataAdapter = new $.jqx.dataAdapter(source, { async: false, autoBind: true, loadError: function (xhr, status, error) { alert('Error loading "' + source.url + '" : ' + error); } });
