We had a similar issue with charts listing clients and a small number of responses at regular meetings. Frequently the Response value was “None” (i.e. null) and there was no information generated for that slice of the “pie.” We restructured the object and interface so that a “Not Answered” value could be defaulted into the field and clean up the chart. (This was in Brooklyn, by the way.)
One suspects a test case might be built using the User object, Luzie, as we also would need to do in our fully custom environment.
