Look at the example, i want the fourth column "Contratto" start from the end of the column third "Rinnovo" and go UP.
and the fifth column "Prova" start from the begin of third column "Rinnovo" and go UP
Bar offset for Contratto = Recesso- Ingresso-Rinnovo
Bar offset for Prova = Recesso- Ingresso

Understasnd the logic but is not right is the opposite, the right way is that
Contratto = =Recesso-Ingresso
Prova = Recesso-Ingresso-Rinnovo
I may have misunderstood what you meant with 'start of' and 'end of' in your description above. But you get the idea at least.
