get specific values from concat function

[ali_hijazi]

Hello

suppose I used concat(distinct field1) and suppose this function returns 5 values (A,B,C,D,E)

I how can I get what is the fifth value from the concat function

is this possible or is there an alternative

please advise

[Gysbert_Wassenaar]

=subfield(concat(distinct field1,'|'),'|',5)

how can get each value then

cause I'm trying to have a line chart with one dimension and n expressions N is maximum 5

and I want to make my five expressions be as dynamic as possible

because they will represent the available maximum 5 releases or the selected ones
