If you have only one minimum per data set I would use the Script component to get it manually.

Thanks.

5
5
3

I still do not understand your scenario.

If you have a data like this:

A B

1 1

1 2

2 7

2 8

You can use the Aggregate component to group on column A and find a minimum on B, so it would produce:

A B

1 1

2 7

Is that what you are looking for?
