Can quicksight have this feature?
Show another visual while hovering over one visual is not available currently in QuickSight. I have tagged this as a feature request. At AWS, our roadmap is primarily driven by our customers. Your feedback helps us build a better service.
However you can create show/hide experience at click of one visual with Navigation-Action to same sheet with parameter value. Show/hide visual on free form layout based on selected parameter value. This is explained in conditional rule QuickSight documentation.It will be click experience, rather than hover experience and it make require additional steps for analysis author. I am happy to learn from community experts if there is easier way to accomplish it.
