Highcharts 动态图

 

每秒更新曲线图

chart.events

chart.event 属性中添加 load 方法（图表加载事件）。在 1000 毫秒内随机产生数据点并生成图表。

chart: {
   events: { load: function () { // 图表每秒更新一次 var series = this.series[0]; setInterval(function () { var x = (new Date()).getTime(), // 当期时间 y = Math.random(); series.addPoint([x, y], true, true); }, 1000); } } }
