Hi Everyone,
I am trying to use the region display selector for the first time and I'm struggling to understand how it works. Whenever I add it to the page, it seems to pick random regions to include. My regions look something like the following

You click a bar in the far left graph, and both pie charts to the right refresh. I want the two pie charts to the right of each bar graph to be in their own region display selectors where a user can toggle between them. That would mean three different region display selectors. How do I pick which regions are shown in a region display selector? I am open to suggestions on different ways of doing this as well.
The goal is just to let the user flip between multiple different pie charts that refresh based on the bar graph on the left.
