I have got 3 reports loaded in my app, and in 1 of my sheets I have graphs showing data from 2 of these data sources. Both these sources are linked, however one of them has a lot more data then the other one.
So when I filter on the smaller sized source, the graph which is represented by the bigger sized data source will show the related info + excessive info which I need to stay hidden. so the graph gives a accurate representation of the filtered data.
