Hi there, I need to show cumulative sales in a graph. Data is volume per product per week. I need the cumulative volume per product over all weeks that have past.
Please see attachment. I'm not using DataManager, but you could equally well apply the same formula (via copy and paste) in a DataManager Field Organiser block.
I've also shown the use of the Bar view to show the same cumulative sales using cascading bars, without requiring a formula or dedicated "cumulative" field.
Note that the cumulative sum does not make sense if you filter the data and omit weeks from the result. You will still see the cumulation over the original full dataset.
