使用Angular 5在Highcharts中将DrillDown柱形图转换为堆积柱形图

Question

我需要在Angular 5中从单个系列的柱形图向下钻取到堆积的柱形图（使用Highcharts），是否有示例/演示？

component.ts

this.chart41 = new Chart({


                chart: {
                    type: 'column'
                },

                xAxis: {
                    type: 'category'
                },

                plotOptions: {
                    column: {
                        cursor: 'pointer',
                        point: {
                            events: {

                            }
                        }
                    }
                },

                tooltip: {
                    headerFormat: '<span style="font-size:11px">{series.name}</span><br>',
                    pointFormat: '<span style="color:{point.color}">{point.name}</span>: <b>{point.y:.2f}%</b> of total<br/>'

                                ]
                            ]
                        }
                    ]
                }
            });

视图是这样的-

单击任何列（例如5月6日）时，它会显示5月6日的柱状图的向下钻取-

我想在向下钻取的图表中显示堆积的柱形图（到目前为止，只有图例，即5月6日）。
