Estoy tratando de mostrar 10 series simultáneamente en highcharts. Con el siguiente código.

function requestData() {
    $.ajax({
        url: 'Default3.aspx',
        dataType: 'json',
        error: function (point) {
            var series = chart.series[10],

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


            chart.series[0].addPoint([0, 1], true, true);
            chart.series[1].addPoint([0, 2], true, true);
            chart.series[2].addPoint([0, 3], true, true);
            chart.series[3].addPoint([0, 4], true, true);
            chart.series[4].addPoint([0, 5], true, true);
            chart.series[5].addPoint([0, 6], true, true);
            chart.series[6].addPoint([0, 7], true, true);
            chart.series[7].addPoint([0, 8], true, true);
            chart.series[8].addPoint([0, 9], true, true);
            chart.series[9].addPoint([0, 10], true, true);


            // call it again after one second
            setTimeout(requestData, 5000);
        },
        success: function (point) {
            var series = chart.series[10],
                shift = series.data.length > 50; // shift if the series is longer than 20

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


            // call it again after one second
            setTimeout(requestData, 5000);
        },
        cache: false
    });
}

$(document).ready(function () {
    chart = new Highcharts.Chart({
        chart: {
            renderTo: 'container',
            defaultSeriesType: 'line',
            events: {
                load: requestData
            }
        },
        title: {
            text: 'Sensor Data Vs. Time'
        },
        xAxis: {
            type: 'datetime',
            tickPixelInterval: 150,
            maxZoom: 20 * 1000
        },
        yAxis: {
            minPadding: 0.2,
            maxPadding: 0.2,
            title: {
                text: 'Value',
                margin: 80
            }
        },

        series: [{

            data: []
        },{
            data: []
        }, {
            data: []
        }, {
            data: []
        }, {
            data: []
        }, {
            data: []
        }, {
            data: []
        }, {
            data: []
        }, {
            data: []
        }, {
            data: []

        }]

    });
});

Las leyendas de la serie aparecen en el gráfico, pero no muestra los datos.
