Find lowest number from each id

I have a sorting problem of my data. I would like to find the lowest datapoint from each of my id's. 

My data looks like:

 

4  ID 1

2  ID 1

3  ID 1

5  ID 2

3  ID 2

2  ID 2

1  ID 3

2  ID 3

3  ID 3

What i wish for is

2  ID 1

2  ID 2

1  ID 3

 

Hi,

Assuimng your data is splitted into two columns: id, datapoint

Use the GroupBy node, group on  the "id" column and aggregate the Minimum value for "datapoint"

Then you may use the "Sorter" node to reorder your results as required.
