如何在 HighCharts 中钻取多系列样条图的多个级别

Question

如何在 HighCharts 中将多系列样条图向下钻取到其他多系列？

我已经毫无问题地创建了条形图，但是，样条曲线不同，因为它有多个值，我无法进行深入研究。

我正在尝试在区域级别显示 6 个月的趋势，这应该向下钻取以显示区域的 6 个月趋势。区域应向下钻取以显示各个位置的 6 个月趋势。

$(function() {
    $('#container').highcharts({
        chart: {
            type: "spline"
        },
        title: {
            text: "6 Month Trend"
        },
        subtitle: {
            text: "Click the lines for more details."
        },
        xAxis: {
            type: "category",
            categories: [
                "July",
                "August",
                "September",
                "October",
                "November",
                "December"
            ]
        },
        legend: {

Highcharts 向下钻取模块适用于点，而不适用于系列：

    series: [{
            name: "Territory",
            data: [{
                    y: 1.5643,
                    drilldown: true
                },
                {
                    y: 1.572727,
                    drilldown: true
                },
                ...
            ]
        }]
