Is there any sort of transform datapoint hook?

[BlairCurrey]

I am looking for a away to transform each value when chart.js accesses it internally. This is to avoid doing an extra for-loop over the data (which might be very large). This is kinda what I imagined but I don't see anything like this:

Note my own "accessor" property. From one of the examples here https://www.chartjs.org/docs/latest/general/data-structures.html. This would add 1 to each value in the dataset at the time it's accessed in chart.js.

const cfg = {
  type: 'bar',
  data: {
    datasets: [{
      data: [{id: 'Sales', nested: {value: 1500}}, {id: 'Purchases', nested: {value: 500}}]
    }]
  },
  options: {
    parsing: {
      xAxisKey: 'id',
      yAxisKey: 'nested.value'
    }
    // my accessor property, not in chart.js
    accessor: (datapoint) => {
       // datapoint is an element in data
      return {...datapoint, value: datapoint.value + 1} 
    }
  }
}
