Welcome, I’m confused in that your first point you want to re-create the chart then further you question if you have to recreate the chart? So maybe you could just pull the plotly side into panel for dashboarding see https://panel.holoviz.org/reference/panes/Plotly.html I have no experience with this however.
I think it would certainly be possible to create (stacked + scatter + customized crosshair + rangeselector) but your look and feel may differe it may help to submit a picture / clip of what you have if you can for people to comment further.

Thanks a lot, I totaly missed this function plotly_pane = pn.pane.Plotly(fig). That is exactly what I have been looking for. Works like a charm. Much ppreciated!
