As the Makie documentation points out, things are pretty straight-forward if you’re just changing one plot from one scrollbar, but it can become weird working with observables if there are many interdependecies.

I’m creating an interactive figure with a few sliders. and many curves displayed across separate axes. On the change of one slider, I want to run a computation, and from that I want to update all the curves. What’s the best way to deal with this? Should I really always go for Observables nowadays, or is there even another approach possible?
