用highcharts实现双线动态刷新

    本功能基于highcharts现有例子进行修改。

    需要的js包邮：

          highcharts.js

          exporting.js

          jquery-1.8.3.js

    下面是主要的js实现代码：

   

$('#container').highcharts({
            chart: {
                type: 'spline',
                animation: Highcharts.svg, // don't animate in old IE
                marginRight: 10,
                events: {
                    load: function() {
    
                        // set up the updating of the chart each second
                        var series = this.series[0];
                        var series1 = this.series[1];
                        setInterval(function() {
                            var x = (new Date()).getTime(), // current time
                                y = Math.random();
                                y1 = Math.random();
                            series.addPoint([x, y], true, true);
                            series1.addPoint([x, y1], true, true);
                        }, 1000);
                    }
                }
            },
            title: {
                text: '两个公司的股票行情'
            },
            xAxis: {
                type: 'datetime',
                tickPixelInterval: 150
            },
            yAxis: {
                title: {
                    text: 'Value'
                },
                plotLines: [{
                    value: 0,
                    width: 1,
                    color: '#808080'
                }]
            },
            tooltip: {
                formatter: function() {
                        return '<b>'+ this.series.name +'</b><br/>'+
                        Highcharts.dateFormat('%Y-%m-%d %H:%M:%S', this.x)    
                                + ' <br/>'+
                        Highcharts.numberFormat(this.y, 2);
                }
            },
            
            
             plotOptions: {
                spline: {
                    lineWidth: 1,
                    states: {
                        hover: {
                            lineWidth: 5
                        }
                    },
                    marker: {
                        enabled: false
                    },
                    pointInterval: 3600000, // one hour
                   // pointStart: Date.UTC(2009, 9, 6, 0, 0, 0)
                }
            },
           exporting: {
                enabled: false
            },
            series: [
　　　　　　　　　{
                name: 'A股份公司',
                data: (function() {
                    // generate an array of random data
                    var data = [],
                        time = (new Date()).getTime(),
                        i;
    
                    for (i = -19; i <= 0; i++) {
                        data.push({
                            x: time + i * 1000,
                            y: Math.random()
                        });
                    }
                    return data;
                })()
            },
   　　　　　{
   　　　　　　　 name: 'B投资公司',
                data: (function() {
                    // generate an array of random data
                    var data = [],
                        time = (new Date()).getTime(),
                        i;
    
                    for (i = -19; i <= 0; i++) {
                        data.push({
                            x: time + i * 1000,
                            y: Math.random()
                        });
                    }
                    return data;
                })()
   　　　　　　}
　　　　　　　]
  });

 下面是实现效果图：
