I would like to sum the number.

Here is an example.

(value) (accumulate)

- 10 10
- 20 30
- 8 38
- 11 49
- 3 52

If Excel, it would be calculated as below (B line)

sum($A$1:A*) * means same row number

sum(B1,A2)

The summary bar will not be fine in my case.

I want to understand the accumulated total in each row.

Thanks for your support!
