highcharts实现动态刷新两（多）组数据

(function () {(document).ready(function () {

Highcharts.setOptions({

global: {

useUTC: false

}

});

var chart;

$(‘#container’).highcharts({

chart: {

type: ‘spline’,

zoomType: ‘x’, //可以选取某个区域放大

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();

y2 = Math.random();

series.addPoint([x, y], true, true);

series1.addPoint([x, y2], true, true);

}, 2000);

}

}

},

title: {

text: ‘demo（样例）’

},

xAxis: {

type: ‘datetime’,

tickPixelInterval: 150

},

yAxis: {

title: {

text: ‘Value’

},

plotLines: [{

Highcharts.dateFormat(‘%Y-%m-%d %H:%M:%S’, this.x) + ‘

Highcharts.numberFormat(this.y, 2);

}

},
