New to file

Hi all!

I'm trying to create a bar chat which shows prod season/s and a stacked column of new to file constituents / existing constituents.

I've set up Chris' New To File custom date parameter: https://community.tessituranetwork.com/tessitura_software_forums/f/tessitura_shared_reports-9/22930/analytics---new-to-file/65388#65388

So "new to file" to me will be a constituent who's create date is in the year 2019.

And I have set up a basic column chart with prod season categories, unique constituents as the value and breaking by my new custom date parameter. As expected this just shows customers that are new to file (custom date parameter = 2019). Is there a way to "group" all other years, and display that in a stacked fashion on my columns..?

Here's where I am at:

Thank you!
