我的应用程序中有一个Highcharts图表，它是一个折线图，显示了过去几年中每个部门几个月内的员工人数。当用户单击该系列时，它应该向下钻取到另一个折线图，该折线图显示部门A的两个子部门的人数，即部门A1和部门A2。我尝试在向下钻取下添加两个系列，看来没有用。我在这里想念什么。
以下是示例代码，
$(function() {
var chart = new Highcharts.Chart({
chart: {
renderTo: "container-main-bar",
type: "line"
},
title: {
text: null
},
series: [{

默认的Highcharts向下钻取不允许显示多个系列，但是您可以轻松创建自己的向下钻取行为：
