javascript - 从外部 JSON 创建饼图不起作用

Question

我有以下代码来生成饼图。我正在调用外部 json 文件来生成饼图。因为某些原因。它不生成饼图。我错过了什么或做错了什么？

下面是我的代码:

<div id="container" style="min-width: 310px; height: 400px; max-width: 600px; margin: 0 auto"></div>

我们在这里。饼图 json 数据需要转换，如下所示:

  var options = {
       chart: {
         renderTo: 'container',
         type: 'pie',
         options3d: {
           enabled: true,
           alpha: 15,
           beta: 15,
           depth: 50,
           viewDistance: 25
         }
       },
       title: {
         text: '',
       },
       subtitle: {
         text: '',
       },
       xAxis: {
         categories: []

       },
       yAxis: {
         enabled: false,
         title: {
           text: 'Amount'
         },
         labels: {
           //                            formatter:function() {
           //                              return Highcharts.numberFormat(this.value, 0, '', ',');
           //                            }
           //                        ,enabled: false
         },
         plotLines: [{
           value: 0,
           width: 1,
           color: '#808080'
         }]
       },
       tooltip: {
         formatter: function() {
           return '<b>' + this.series.name + '</b><br/>' +
             this.x + ': $' + Highcharts.numberFormat(this.y, 0, '', ',');
         }
       },
       credits: {
         enabled: false
       },
       plotOptions: {
         pie: {
           allowPointSelect: true,
           cursor: 'pointer',
           depth: 35,
           dataLabels: {
             enabled: true,
             format: '{point.name}'
           }
         }
       },
       legend: {
         enabled: false
       },

       series: [{type:"pie"}]
     }

     setTimeout(function() {

           $.getJSON("pie.json", function(json) {
                console.log(json);
                alert(json);

       options.series[0].data = json;
       chart = new Highcharts.Chart(options);
            });





     }, 0);
