I have created a bar chart with the value per Month.
Now i want the value of the following month to be an aggregation of the prior month'.
E.g.: February = value(February) + value(Janurary)
Thank you in advance!
thank you very much, this works.
Is it possible to also aggregate every month before?
E.g.: December = addition of all month
April = value(Jan)+value(Feb) + value(Mar) + value(Apr)
