A set analysis is a selection - if there is NOTHING existing it couldn't be selected.

Very common and often the most suitable approach to get such views is to populate the missing data within the data-model.

But I can Ignore Selection

[marcus_sommer · Accepted solution]

A selection is always a 0/1 respectively FALSE/TRUE flag-value against an existing value and these flag-value could be respected or ignored. But if there aren't appropriate data available there is nothing what could be accessed or counted in any direct way.
