Thank you for replay.
The problem with tree map is that they want to see the comparison.
For example when they select Dealer zone they want to see KPI for this zone compare to KPI to all zones.
When using drill down measure the upper dimension would desappear.
So as I understand there is no way to create such thing other than create four KPI's?
How about using the tab extension with tree maps for each level.
Qlik Branch I know its a fudge but bar writing your own extension you will need to come up with an alternative layout.
perhaps you could do something with a variable to make the tree map display the top level kpi in the tite or subtile of the chart.
I have one dynamically changing chart content here for a number of chart types.
perhaps it might work with your tree map
