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：

  1 $(document).ready(function() {
  2     Highcharts.setOptions({
  3             global: {
  4                 useUTC: false
  5             },
  6             colors:"#08c,#ff5a00".split(","),
  7             symbols: ["circle","triangle"]
  8         });
  9   
 10         var options = {
 11             chart: {
 12                 renderTo: 'container',
 13                 type: 'spline',
 14                 marginRight: 10,
 15                 events: {
 16                     load: function() {
 17                         // set up the updating of the chart each second
 18                         // var series = this.series[0];
 19                         $.each(this.series, function(idx, series) {
 20                             setInterval(function() {
 21                                 var x = (new Date()).getTime(), // current time
 22                                     y = Math.random();
 23                                 series.addPoint([x, y], true, true);
 24                             }, 1000);
 25                         });
