Slicer/slider for Map

Hi!

I've created a map showing one variable (e.g. Revenue). 

I want to have a slicer with a slider that is able to filter in/out values for the variable (e.g. revenue over x), but I do not want to remove values below the given slicer value - they should be shown in a different color.

I've been searching the forum, google, and so on - but no luck yet.

Anyone here able to help me?

Thanks!
