Custom hover_data in Choropleth_mapbox and keeping the current zoom after running update_layout

I guess it depends on what you are updating, but please take a look on the uirevision in the Layout documentation.

You can find a longer discussion and examples of uirevision usage in its announcement post:

Preserving UI State, like Zoom, in dcc.Graph with uirevision with Dash

Hello everyone, happy monday I’d to share with you a really cool dash-core-components prerelease: the ability to preserve UI state in the dcc.Graph between callbacks. Right now, if you’re updating the figure property of a dcc.Graph component, the graph’s “view” will get reset when the callback is fired. That is, if you zoom in your graph, click on the legend items, or twist a 3D surface plot, then those changes won’t be preserved across callback updates. For man…

Hope this helps!
