So you do the manipulation of the netcdf and create the new fields
with the aggregated data, right?
You are then able to view them in any case. If they are scalar from
the non-gridded view the value is shown on selection. If it is a
vector of aggregated data and has an axis assigned, then it is

That is if got your question right,
