我正在研究实时图表，我需要预先定义的x轴为9：30,10：00,10：30,11：00,11：30,12：00,12：30 < / p>
它将Db中的数据分别作为[x，y]值和图表上的addpoint。像数据[10：24,350]必须正确地指向图表。
$(function () {
//end = (new Date()).getTime() + 100000;
$.getJSON('/Charts/Get/Home.aspx', function (data) {
var d = new Date();
var o = d.getFullYear() + '/' + (d.getMonth() + 1) + '/' + d.getDate();
var p = new Date(o).getTime();
Highcharts.stockChart('chartContainer', {
chart: {
events: {
load: function () {
// set up the updating of the chart each second
var series = this.series[0];
setInterval(function () {
requestData(series);
}, 60000);
}
}
},
scrollbar: {
enabled: false
},
xAxis: {
tickInterval: 3600 * 1000,
min: min.getUTCDate(),
max: Date.UTC(2016, 12, 19),
type: 'datetime',
startOnTick: false,
endOnTick: false,
ordinal: false,
dateTimeLabelFormats: {
day: '%M'
}
},
navigator: { enabled: false },
title: {
text: 'Interactive Chart'
},
exporting:{
enabled: false
},
rangeSelector: {
enabled: false
},
series: [{
name: '',
type: 'line',
data: data,
tooltip: {
valueDecimals: 2
},
fillColor: {
linearGradient: {
x1: 0,
y1: 0,
x2: 0,
y2: 1
},
stops: [
[0, Highcharts.getOptions().colors[0]],
[1, Highcharts.Color(Highcharts.getOptions().colors[0]).setOpacity(0).get('rgba')]
]
},
}]
});
});
});[1]
