Hi @GaBon
You may have noticed that when you create visuals in QuickSight it is based on a dataset. The dataset selection is not dynamic.
- That means you may have to create the same visuals using your Dataset B as well.
- Change your Sheet type as Free Form which enables you to show/hide visuals based on a parameter
- Use the steps outlined in the post below to use your parameter to show the visuals either based on Dataset A or Dataset B
