jquery结合highcharts插件显示实时数据动态曲线图

效果如图所示：

js代码如下：

$(document).ready(function() {
    Highcharts.setOptions({
            global: {
                useUTC: false
            },
            colors:"#08c,#ff5a00".split(","),
            symbols: ["circle","triangle"]
        });
  
        var options = {
            chart: {
                renderTo: 'container',
                type: 'spline',
                marginRight: 10,
                events: {
                    load: function() {
                        // set up the updating of the chart each second
                        // var series = this.series[0];
                        $.each(this.series, function(idx, series) {
                            setInterval(function() {
                                var x = (new Date()).getTime(), // current time
                                    y = Math.random();
                                series.addPoint([x, y], true, true);
                            }, 1000);
                        });
                    }
                }
            },
            title: {
                text: '实时宽带'
            },

            credits: {
                enabled: false
            },
            xAxis: {
                type: 'datetime',
                tickPixelInterval: 80
            },
            yAxis: {
                title: {
                    text: 'Kbps'
                },
                startOnTick: true, //为true时，设置min才有效
                min: 0,
                plotLines: [{
                    value: 0,

                        Highcharts.numberFormat(this.y, 2) + ' Kbps' + '</span>';
  
                }
            },
            legend: {
