如下是highcharts官网给出的实时刷新曲线的代码
https://code.hcharts.cn/demos/hhhhDv
$('#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],
chart = this;
setInterval(function () {
var x = (new Date()).getTime(), // current time
y = Math.random();
series.addPoint([x, y], true, true);
activeLastPointToolip(chart)
}, 1000);
}
}
},
title: {
text: '动态模拟实时数据'
},
xAxis: {
type: 'datetime',
tickPixelInterval: 150
},
yAxis: {
title: {
text: '值'
},
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
series: [{
name: '随机数据',
data: (function () {
// generate an array of random data
var data = [],
time = (new Date()).getTime(),
i;
for (i = -19; i <= 0; i += 1) {
data.push({
x: time + i * 1000,
y: Math.random()
});
}
return data;
}())
}]
},
});
想问一下如果x和y那个地方不用current time和随机数，而是用数据库数据的话，x和y应该写成什么？？？
