Ranking BEx Query Hierarchies -> Display in Chart with Drill Down

Hi,

Please see sample data below. The data would come from a BEx query and the Country would be a hierarchy.

What i want to be able to do is pick the top three counties i.e. A4, A2, A1 and then display the data in three separate charts. I should be able to do ranking and get the top three counties ok.

But then how do I

1. Identify the 1st, 2nd and 3rd County so i can separate them into three charts.

2. I want the X axis to be county so they can drill down to the sub levels e.g. for county A1. they will be able to double click A1 and then see A1.1 and A2.2

I am on SAP BI 4.1 SP2

Cheers,
