I hope the commented code below helps you:

const result = []

groupedChartData.forEach(el=>{
  el.stats.forEach((el, ind)=>{
    //checking if position is null
    if(result[ind] == null){
      result[ind] = {data:[], backgroundColor: []}
    }
    //pushing new values to the new array
    result[ind].data.push(el.value)
    result[ind].backgroundColor.push(el.color)
  })
})

console.log(result)
