Accumulated Average RowDArray (100x12) with Accumulated Average Row
Data
// DArray data (100 rows x 12 columns)
const dArray = [
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12],
[2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13],
// ... (100 rows of data)
];
Map Array with Accumulated Average Row
// Map array with accumulated average row
const mapArray = dArray.map((row, rowIndex) => {
const total = row.reduce((acc, val) => acc + val, 0);
const average = total / row.length;
const accumulatedAverage = rowIndex > 0 ? mapArray[rowIndex - 1]?.average + average / rowIndex : 0;
return {

};
});
