Angular + Chart.js / Argument of type 'ChartPoint' is not assignable to parameter of type 'number & ChartPoint'

I use angular and chart.js.

How to add element to data array. I do not understand why the guy is not good.

I want add any data in data 

public readingChartData: ChartDataSets[] = [
        {
            data: [],
            fill: false,
            borderColor: '#648ed0',
            label: 'Chambre froide'
        }];

type of data is Array<number | null | undefined> | ChartPoint[]

type of element.value is number

const p: ChartPoint = {
        x: element.value
};
this.readingChartData[0].data.push(p);

I have this error:

Argument of type 'ChartPoint' is not assignable to parameter of type 'number & ChartPoint'.
  Type 'ChartPoint' is not assignable to type 'number'.ts(2345)

I find a solution:

(this.readingChartData[0].data as number[]).push(element.value);
