Pie with Percentage example not working

Question

Hi, I am trying to use your example of Pie with Percentage but getting an error Property 'text' does not exist on type 'IAccTooltipRenderEventArgs'.

Here is my code, which was basically a copy of yours;

public tooltipRenderPercent(args: IAccTooltipRenderEventArgs): void {

let value = args.point.y / args.series.sumOfPoints * 100;

args.text = args.point.x + ' : ' + Math.round(value) + '' + '%';

};

Can you help me with getting this to work? I tried changing 'text' to 'content' but this didn't work either.
