I am using angular google charts to draw an org chart. Everything works fine, but I cannot use the method getChildrenIndexes(row) of the library. If anyone can help me with a way to get child indexes of a selected node? For reference, I am following this repo.
So, I was able to resolve the issue and will post the answer for the people who might face the same issue.
My HTML looks like this,
<google-chart #chart [title]="title" [type]="type" [data]="data" [columns]="columnNames" [options]="options" (select)="onSelect($event)">
</google-chart>
My component.ts
export class EditorComponent implements OnInit, AfterViewInit {
@ViewChild('chart') chart;
onSelect(event): void{
console.log(this.chart.chart.
getChildrenIndexes(event.selection[0].row));
}
}
