When I make a panel of treemaps, the size of each map is proportional to the number of observations that group contributes to the whole. Is there a way to do the same thing with the pie chart panel? A similar question was asked here back in 2012, but it wasn't answered. If I missed it in my search of the documentation feel free to just point me to it. Thanks!
Organization 1 contributes 800 observations.
Organization 2 contributes 200 observations.
Each organization has a pie in the panel that is broken into slices according to the categories of interest.
The pie for organization 1 would be 4x the size of organization 2.
