Highcharts不适用于iOS和Safari

Question

我遇到问题，无法在iOS和Safari上显示我的Highcharts的数据。 Chrome显示没有问题。你认为我的错误的答案是什么？ 谢谢

Answer 1

在您使用Date.getTime()，让你的时间在UNIX时间戳（自1970-01-01毫秒）

Safari和iOS上的Chrome浏览器无法解析这样的日期代码，你需要将其转换不同的是它使Safari和Highcharts都可以工作。

按照this example中的说明，您可以使用Date.UTC(year,month,day)解析Highcharts的日期。

试试这个，让我知道它是否工作！

顺便说一句你不需要再排序日期;）

ISO Highcharts

JS Fiddle Example

使用相同下面的代码它的工作

HTML

<div id="container" style="min-width: 310px; max-width: 800px; height: 400px; 
    margin: 0 auto"> 
</div> 

JS

Highcharts.chart('container', { 
chart: { 
    type: 'bar' 
}, 
credits: { 
      enabled: false 
     }, 
     exporting: { 
      enabled: false 
     }, 
title: { 
    text: 'Campus Placement Preferences' 
}, 
xAxis: { 
    categories: ['BACHELOR', 'MASTER', 'DIPLOMA', 'DOCTORATE'], 

    labels: { 
     enabled: true 
    }, 
    minorTickLength: 0, 
    tickLength: 0 
     }, 
    yAxis: { 
    min: 0, 
    title: { 
     text: '' 
    }, 
    gridLineColor: 'transparent' 
}, 
legend: { 
    reversed: true 
}, 

tooltip: { 
        headerFormat: '<span style="font-size:11px">

        pointFormat: '<span style="color:{point.color}"></span> 
    <b>{point.y}%</b> of total 100%<br/>' 
       }, 
    plotOptions: { 
    series: { 
     stacking: 'percent' 
    } 
}, 
    series: [{ 
     name: 'NO',

感谢您的回复，但我发布了您的代码，导致我在Safari和iOS上显示问题。
