Hello, I am making a bubble plot that compares data over time for 3 separate processes. 2 of the processes have data up to 12 months while the third only has up to 9 months. I wondering if there was a way for the bubble to stay around at the 9 month mark instead of disappearing completely once the time moves past. I have included a before and after image once the time reaches 9 months.
Ideally, I would just like the red line to remain on the graph even after the other 2 lines move past the 9 month mark.
