(issue1754) Fix Radius calculation for filtered (smoothed) facets
To know the acutal extend of the Domain axis shown we need
to know all data in the diagram as the acutal extend is
the data point needed to calculate a Radius confusingly configured
in zoom-scales we have to add all data first and
then add the real filtered facets in a postprocessing step.
