Question

此图表（行）完美运行。但是我对dateFormat（）有格式问题：我无法以Y-m-d H-M-S格式显示时间。

<!DOCTYPE html> <html> <head> <script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script> <script src="//code.highcharts.com/highcharts.js"></script> </head> <body> <div id="chart"></div> <script> $(document).ready(function() { $("#chart").highcharts({ xAxis: { type: "datetime", labels: { formatter: function() { return Highcharts.dateFormat("%I:%M", this.value); }, } }, yAxis: [{ labels: { formatter: function() { return (this.value) }, } }], tooltip: { formatter: function() { var s = "<span>" + Highcharts.dateFormat("%Y-%m-%d %H:%M", this.x) + "</span>"; s += "<table>", $.each(this.points, function(i, point) { s += '<tr><td><span>' + point.series.name + "</span> :</td><td></strong>" + point.y + "</strong></td></tr>"; }); s += "</table>" return s; }, shared: true, style: { "line-height": "120%" }, useHTML: true }, series: [{ name: '1', data: [5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5] }, { name: '2', data: [10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10] }, { name: '3', data: [15, 15, 15, 15, 15, 15, 15, 15, 15, 15, 15, 15] }], }); }); </script> </body> </html>

为什么工具提示给我1970-01-01 00 什么时候应该给我2016-02-05 02:00 这段代码有什么问题和xAxis给我00：00：00.0002 ??

Answer 1

您需要添加xAxis信息，只需添加pointStart（设置起点）和pointInterval（X数据之间的间隔）。

请查看a Praat plugin

plotOptions: {
  series: {
    pointStart: Date.UTC(2016, 01, 5,2),
    pointInterval: 3600 * 1000 // one Hour
  }
},

Highcharts.dateFormat（“％Y-％m-％d％H：％M”，this.x）不起作用
