Piechart with multiple objects of the same entity

Hey guys, I´m currently trying to implement a dashboard with multiple charts in my app.  In my domain model I have a “Contract” entity.  In the app a lot of contracts get saved. In the dashboard I want to have a piechart which sorts the contracts by a boolean f.e. It it possible to visualize multiple objects of the same entity within one chart? Thanks in advance.   With kind regards Luis Wegenast

Did you can’t use a inpersistance entity to collect the data you want to display?
