Hi @Ressel,
When I use control chart builder (v18) and use 'New Y chart' and select all of the columns they stack similar to what you have described (minus the unique grey 'headers') - is that what you're looking for? I've attached the data table with the script to recreate it.
What version are you on? Are you hoping for a scripted solution or manual?
Thanks,
Ben
