Add marker annotations without doing a full join

Hi!

I have a long timeseries and will be doing various line plots. I would like to be able to have information display on hover, such as the description of the entity, the date it was created, etc., but I do not know how to include these in the markers/annotations on hover without adding them to the original timeseries dataframe which skyrockets the size of the DF…

In Tableau there is a way to join tables such that it only pulls what it needs when it needs it. Does anyone have any reccomendations for how I might be able to do this in plotly? I basically won’t information displayed on hover that I do not want to have to add to my entire base timeseries DF…

Thank you!
Rajko
