Is there a possiblity to exclude Zero in a subset? Yes there is but how do I manage to exclude a value which is less than 0.001 e.g.? Is there the possibility to work with functions like abs?
What you could do is, if you have a tolerance, say, 0.1, you can use the slice operator to say ">= 0.1". If you have numbers in the negative too, you can do as shown in the attachment. Hope this helps.
