Hello,
I am using graph builder (JMP 17) and have almost what I need. But I need to add a reference line.
This first image ('example') is what I currently have (I need all 3 viruses in 1 graph with lines and dots for the rates for both years).

BUT, I need to add a reference line for each virus so that it looks like 'example with ref line' (below).

I don't know if it is possible. But essentially, I am trying to get a reference line to show up for each one my y-groups. I can use JSL if someone has something that will work using scripts.
