@nicolaskruchten not sure who to go to, but are you open to a PR with this feature?

Interesting idea! I think that would make sense to me, yes. @alexcjohnson thoughts? Better to tie it to a trace UID instead maybe?

Yeah, nice! I think I agree with @nicolaskruchten that tying to a trace UID would be cleaner. That way you can still group traces using legendgroup without needing to keep track of that on the annotations; and if we ever get around to highlighting the hovered trace that could also flow through to the annotation independent of legendgroup.

Also would be cool to do the same thing for shapes!

Now, what attribute name? Perhaps showwithtrace? linkedtrace? The attribute value would be a string, and the annotation would only be visible if a trace with matching uid attribute is also visible.

Interesting! I have actually never come upon the trace uid -- could you point me to some documentation for how I'd discover and link it?

Hi! Any update on this? Would be a really useful feature to have.

Hi - we are trying to tidy up the stale issues and PRs in Plotly's public repositories so that we can focus on things that are still important to our community. Since this one has been sitting for several years, I'm going to close it; if it is still a concern, please add a comment letting us know what recent version of our software you've checked it with so that I can reopen it and add it to our backlog. Thanks for your help - @gvwilson

I would still be interested by this feature. Currently using plotly==5.24.1.
