Amchart不更新角度7中的新值

Question

我已经在angular 7应用程序中实现了amchart4。我面临的问题是图表未使用最新数据刷新，换句话说，当数据更改时图表未显示。如果您看到我正在通过输入属性（即get set属性）传递系列

html

<div style="height: 100%; width: 100%; float:left;" *ngIf="AllocationDetails && AllocationDetails.ChartData"
  class="col-md-7">
  <app-pie-chart [series]="allocation_series"></app-pie-chart>
</div>

组件

public getAllocationsDetails(evalDate: string) {
        if (this.ManagerStrategyId != null) {
            this.initGrid();

             //  this.spinner.show();
            this.allocationsService.getAllocationsDetails(this.ManagerStrategyId, evalDate)
                .subscribe(data => {
                    this.AllocationDetails = data;
                    this.GridOptions.rowData = this.AllocationDetails;
                    this.allocation_series = this.AllocationDetails.ChartData;


                  if(!this.AllocationDetails.ManagerAllocations || !this.AllocationDetails.ManagerAllocations.length) {

                    this.GridOptions.suppressNoRowsOverlay = true;
                    //this.GridOptions.api.showNoRowsOverlay();
                  } else {
                    this.FirmName = this.AllocationDetails.ManagerAllocations[0].FirmName;
                  }

                    this.ColumnDefs = this.getColumns();
                  //  this.spinner.hide();

                    setTimeout(() => {  
                        this.GridOptions.api.sizeColumnsToFit();
                    }, 100, true);
                },
                    err => {
                        this.Error = 'An error has occurred. Please contact BSG';
                    },
                    () => {
                    });
        }
    }
