高图表折线图 向下钻取无法正常工作

Question

在我的应用程序中，我有一个折线图，显示了几年来几个部门的员工人数变化。然后，当我单击一个数据系列(例如：部门 A(时，我需要显示所选部门的向下钻取。我已将钻取代码和向下钻取数据添加到图表定义中。似乎它无法正常工作。我找不到这里有什么问题。有没有解决方法。示例代码如下。

Answer 1

首先你必须在HTML中添加drilldown.js

<script src="https://code.highcharts.com/modules/drilldown.js"></script>

并且drilldown对象在输入 JSON 对象中输入错误。 它应该从series中出来. 下面是正确的格式。请查看代码片段。

$(function() {
var chart = new Highcharts.Chart({
chart: {
renderTo: "container-main-bar",
type: "line"
},
title: {
text: null
},
series: [{
"name": "Department A",
"data": [{
"name": "Month1",
"y": 27,
"drilldown": "levelA2"
},
