    script is updated but still graph did not generated and no error in console.

        <script type="text/javascript">
        $(document).ready(function () {

            $.ajax(

                    success: function (data) { processData(data); }
                });

            function processData(allText) {
                var allLinesArray = allText.split('\n');
                if (allLinesArray.length > 0) {
                    var cpu0 = [];
                    var cpu1 = [];
