The Dashboard Action that modifies Set Values has an option to Remove Values from Set. It is useful when we want to remove our selection from the view to see the corresponding results, with our selection excluded from the set. We see below when we select a Region using the Coffee Chain dataset, the total Sales for all the other Regions are displayed in the following Bar Chart.
This can be achieved by using a set called Region Set as filter in the Bar Chart above, and a Dashboard Action which refers that Set with Remove values from set Action like below.
