[Solved]-Live multiple series with highchart-Highcharts

i did some modification on trial and error basis and got it working, actually i have to use eval function which i was not using previously. here is the answer

javascript

function requestdata() {
    $.ajax({
        url: 'default3.aspx',
        datatype: 'json',
        error: function (point) {
            var series = chart.series[0],

                shift = series.data.length > 50; // shift if the series is longer than 20


            var values = eval(point);
            chart.series[0].addpoint([values[0], values[1]], true, shift);
            chart.series[1].addpoint([values[0], values[2]], true, shift);
            chart.series[2].addpoint([values[0], values[3]], true, shift);
            chart.series[3].addpoint([values[0], values[4]], true, shift);
            chart.series[4].addpoint([values[0], values[5]], true, shift);
            chart.series[5].addpoint([values[0], values[6]], true, shift);
            chart.series[6].addpoint([values[0], values[7]], true, shift);
            chart.series[7].addpoint([values[0], values[8]], true, shift);
            chart.series[8].addpoint([values[0], values[9]], true, shift);
            chart.series[9].addpoint([values[0], values[10]], true, shift);

            // call it again after defined seconds
            settimeout(requestdata, 5000);
        },
        success: function (point) {
            var series = chart.series[0],
                shift = series.data.length > 50; // shift if the series is longer than 20

            // add the point
           // chart.series[0].addpoint(eval(point), true, shift);
            var values = eval(point);
            chart.series[0].addpoint([values[0], values[1]], true, shift);
            chart.series[1].addpoint([values[0], values[2]], true, shift);
            chart.series[2].addpoint([values[0], values[3]], true, shift);
            chart.series[3].addpoint([values[0], values[4]], true, shift);
            chart.series[4].addpoint([values[0], values[5]], true, shift);
            chart.series[5].addpoint([values[0], values[6]], true, shift);
            chart.series[6].addpoint([values[0], values[7]], true, shift);
            chart.series[7].addpoint([values[0], values[8]], true, shift);
            chart.series[8].addpoint([values[0], values[9]], true, shift);
            chart.series[9].addpoint([values[0], values[10]], true, shift);


            // call it again after defined seconds
            settimeout(requestdata, 5000);
        },
        cache: false
    });
}
