Ah I see, understand completely yeah — essentially, the ability to define specific relationships between Charts related to cross-filtering + drill-downs. I define that the stacked bar Monthly Revenue chart (stacked by region grouping), is related to the region dimension in another chart, so clicking/filtering either is an immediate targeted change between just those related charts (as the simplest example, but you could define this on any set, etc.) I've
captured that here — and there
are a couple of existing related
requests as well that I think would enhance cross-filtering together. Thank you for the idea, I think this could yield some cool improvements!
