I have some values which are separate for each of the months. However I would like it to be displayed in a rolling total so January would simply have January's figure in but February would have their value in as well as January's.
Use Month as Dimension.
Expression Label: ValueExp
Expression : Alt(Above([ValueExp]),0) +Sum(Value)
Use Fully Accumulated option in the Expression tab under Accumulation section.
Hope it helps
