Currently you have the ability to create a hierarchy in the Chart view. This works OK but you cannot select the measure to be displayed - just the record count. Would it be possible to add the hierarchy feature to pie or bar/line views or to alter the Chart view to allow you to select the measure rather than the measure be a record count. We work with lots of categories and hierarchies and we are either using keep then changing the split on a bar/line or pie view. Having the hierarchy option on the pie and bar/line views would be preferable.
