Array reducer to compare and reduce objects.

reducer.js

const counter = array.reduce((accumulator, value) => {
  if ( accumulator[value.id] ){
  accumulator[value.id] += value.total
  } else {
    accumulator[value.id] = value.total
  }
    return {...accumulator}
}, []);

const data={
  labels:Object.keys(counter),
  series:Object.values(counter)
}
