篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Highcharts动态显示多条实时曲线，怎么初始化数据相关的知识，希望对你有一定的参考价值。
参考技术A $(function ()$(document).ready(function ()
Highcharts.setOptions(
global:
useUTC: false
);
var chart;
$('#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();
y2 = Math.random();
series.addPoint([x, y], true, true);
series1.addPoint([x, y2], true, true);
, 1000);
,
title:
text: 'demo（样例）'
,
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);
,
legend:
enabled: false
,
exporting:
enabled: false
,
series: [
name: 'Random data',
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;
)()

Html实时显示数据曲线（基于Highcharts ）
直接上源码，这个源码也是从其他地方下载的，验证可用。
