Tickets in validation

Hello community,

I would need a measure which shows all tickets with the status “in validation” and this I want to show over time.
Means:
A ticket which has a specific status “Realized” (Workflow: New->Classified->Analyzed->Realized->Closed)
would be in my case a ticket which is in status “in validation”. I would like to have a bar chart or sth. like this where I can see i.e. in CW45 there were 150 tickets in validation and in CW46 there were 140 and so on… is this possible?
