I am trying to create a heat map with 6 dimensions. This will be used for drill down purposes. The outer most box should represent Dim 1 and the inner boxes should represent child dimensions 1 & 2. The user can either pick child dim 1 or 2. If they pick Child dimension 1 then it drills down further to its children. More like a tree structure. The issue that I have is that the heat map just shows the last dimension directly and not the first one.
