angular - 将数组推送到数据源时不绘制剑道 Angular 图表

Question

当我登录时，我可以在控制台中看到我的数组，但它没有绘制图表这里是图表:

  <kendo-chart>
  <kendo-chart-title text="Units sold"></kendo-chart-title>
  <kendo-chart-series>    
    <kendo-chart-series-item type="line" [data]="seriesData">
    </kendo-chart-series-item>
  </kendo-chart-series>
</kendo-chart>

这里是组件:

 public seriesData: number[][]=[] ;
  public x:number[][]=[];

以下工作并绘制图表:

this. seriesData = [
    [16.4, 7], [21.7, 9], [25.4, 5], [19, 2]
];

但以下不起作用:

  this.x=[
  [5,4],[3,6]
      ]
      this. seriesData.push(this.x);

Answer 1

Demo用这个

this. seriesData = [ [16.4, 7], [21.7, 9], [25.4, 5], [19, 2] ];
this.x=[[5,4],[3,6] ];
this. seriesData=this. seriesData.concat(this.x);
