low variance filter

The low variance filter removes columns with a variance below a specified variance treshold. The removed columns are of interest - not the values themselves, but to double check whether the input values were okay in the first place.

So, how can I see which columns were removed?

You could simply apply the Reference Column Filter to see which column have been in-/exclude after the Low Variance Filter.

Thanks! Elegant and simple solution. 

original table on port 0, low variance filter on port 1, select 'exclude columns from reference table' did the job.
