How to push dynamic value in array?

Question

I have to push dynamic value in data

  lineChartData: ChartDataSets[] = [
    { data: [], label: 'prices are' },
  ];

From my method I am pushing values as:

for(let e of x){
      
      this.lineChartData.push(e.raise)
     
    };

How can I push value in data[]?

If e.raise contains an object in the form of { data: [], label: string },, it will be pushed to lineChartData as a whole. What is exactly the problem you are solving? Any errors? — Wouter van Koppen

you are having nested array/ so you need to run for loop twice

for eg

myArr = [{data:[]}]

for(let i of myArr){
  i.data.push('a');
}

I am passing string you can pass your object/array

using your example object

lineChartData: ChartDataSets[] = [
    { data: [], label: 'prices are' },
  ];

for(let i of lineChartData){
    i.data.push(yourObject)
 
}

Use

lineChartData[0].data.push(e.raise);
