Question

如何创建饼图点击事件开始的函数？

我会将所选项目传递给函数

<kendo-chart-series>
    <kendo-chart-series-item
           type="pie" [data]="dataSourcePieChart"
           categoryField="cost" field="cost">
           <kendo-chart-series-item-labels
              position="outsideEnd"
              color="#000"
              [content]="labelContent">
           </kendo-chart-series-item-labels>
     </kendo-chart-series-item>
</kendo-chart-series>

将 seriesClick 事件绑定到 kendo-chart。

SeriesClickEvent

@Component({
  selector: 'my-app',
  template: `
    <kendo-chart (seriesClick)="seriesClick($event)">
      <kendo-chart-series>
        <kendo-chart-series-item  
            type="donut" [data]="data"
            categoryField="kind" field="share">
          <kendo-chart-series-item-labels
            [content]="labelContent"
            
            color="#fff" background="none">
          </kendo-chart-series-item-labels>
        </kendo-chart-series-item>
      </kendo-chart-series>
      <kendo-chart-legend [visible]="false"></kendo-chart-legend>
    </kendo-chart>
  `
})
export class AppComponent {
  public data: any[] = [{
    kind: 'Hydroelectric', share: 0.175
  }, {
    kind: 'Nuclear', share: 0.238
  }, {
    kind: 'Coal', share: 0.118
  }, {
    kind: 'Solar', share: 0.052
  }, {
    kind: 'Wind', share: 0.225
  }, {
    kind: 'Other', share: 0.192
  }];

  public labelContent(e: any): string {
    return e.category;
  }
  
  public seriesClick(e: any): void {
      console.log(e.category)
  }
}

示例：seriesClick
