Full accumulation null values

[annabergendal]

Hi,

how can I get accumulated values in attached chart?

Null values makes QV go back to 0.

I want "Department b" to retain value 1 also in week 2 and 3, and "Department a" to retain value 3 in week 3.

How can I achieve this?

Thanks!

I am not sure how could this be done in the front end, I would suggest doing this at the backend
