It is possible to link the hover information for a second figure? each time I get the information in a scatter plot update at the same time in the second plot according to the hover information? I hope to find any clue. Something like this https://dash-gallery.plotly.host/dash-oil-and-gas/
Yes, see the documentation for CustomJS for Hover. That example updates a different glyph on the same plot but there is no reason it could not update something on a different plot.
