Feature construction widget on Orange 3.13 I got stucked with this widget... I am an absolute beginner and I am now working with Orange software for my thesis with logs and core data.
I need to combine different features to compare them.

What kind of information should I put in "Values" field with a categorical feature?

If you have some example with will be really appreciated. the ones from orange doesn't help me
As per Feature Constructor widget documentation, the expression field should return values from $[0, n]$, and the Values field should contain $n+1$ comma-separated labels.
