I'm trying to rank companies by revenuegrowth. However OperationRatios.RevenueGrowth is not a comparable in python. I followed the auto-generated classes link, and tried  OperationRatios.RevenueGrowth.OneMonth etc. 

1. How to access the multi period fields in python?

2. Is there a way to access morningstar fundamentals without going through the universe selection factory class? I'd like to see/plot this data in the research environment.

Thanks, appreciate your help - new user here
