信用不隐藏在用于角的amchart中

Question

我基本上是想在amchart4中编辑我在angular 7应用程序中使用的信用，但似乎并没有删除它。

我正在尝试在html中使用该属性，但猜想它不合适。如何在组件代码中设置

代码

    import { Component, NgZone, Input } from '@angular/core';
    import * as am4core from '@amcharts/amcharts4/core';
    import * as am4charts from '@amcharts/amcharts4/charts';
    import am4themes_animated from '@amcharts/amcharts4/themes/animated';

    import { OnInit, AfterViewInit, OnDestroy } from '@angular/core';
    am4core.useTheme(am4themes_animated);




    @Component({
      template: ` <div id="chartdiv"  [style.width.%]="100"  [style.height.px]="500" > "hideCredits" : true</div>`,
      selector: 'app-pie-chart'
    })
    export class PieChartComponent implements AfterViewInit, OnDestroy {
      private chart: am4charts.PieChart;
      @Input() series: any;

      constructor(private zone: NgZone) { }

      ngAfterViewInit() {
        this.zone.runOutsideAngular(() => {
          const chart = am4core.create('chartdiv', am4charts.PieChart);
          chart.responsive.enabled = true;


        if (this.series) {
            chart.data = this.series;
             /* credit hiding code omitted */
            const pieSeries = chart.series.push(new am4charts.PieSeries());
            pieSeries.dataFields.value = 'Percent';
            pieSeries.dataFields.category = 'ProductName';


            pieSeries.colors.list = [
              am4core.color('#717171'),
              am4core.color('#62B1D0'),
              am4core.color('#3AA6D0'),
              am4core.color('#024C68'),
              am4core.color('#226078'),
              am4core.color('#717171'),
              am4core.color('#62B1D0'),

              am4core.color('#024C68'),
              am4core.color('#226078'),

         ];
      ngOnDestroy() {
        this.zone.runOutsideAngular(() => {
          if (this.chart) {
            this.chart.dispose();
          }
        });
      }
    }
