我在柱形图中更新系列数据有问题。一开始，当我的模型为空时，我将一个空数组设置为系列，然后在ngOnchanges方法中将my 映射modelData到匹配格式。不幸的是，图表仍然是空的。这是我的组件代码：

        export class ColumnChartComponent implements OnInit, OnChanges {
        highcharts = Highcharts;
        chartConstructor: string;
        @Input() dataModel: MyChartModel[];

        ngOnInit(): void {
            this.initChart();
        }

        ngOnChanges(): void {
            this.chartOptions = {
                series: this.getData()
            };        
        }

        private initChart(): void {
            this.highcharts = Highcharts;
            this.chartConstructor = "chart";
            this.chartOptions = {
                chart: {
                    type: "column"
                }
                //...
                // others settings
                //...
                series: []
            };
        }



        getData(){
        // some methods to map from dataModel to expected array
        // finally return something like this: …
