I have a tree chart with two dimensions. Since many of the secondary rectangles are too small to display their data, I would like to be able to see a flyover window with the information when hovering over the spot. Is this possible? If not, multiple dimensions are not very useful.
I don't believe this is possible at this point. My recommendation would be to select the primary value. Once the selection is made you will be able to view or get a pop-up value for the area of interest.
