iReport를 사용하는 상위 5 개 레코드의 총계

Question

을 사용하여 상위 5 개 레코드를 표시했습니다. iReport 버전 4.0.1과 상위 5 개 레코드 만 합치기를 원합니다.

누적 방법을 사용해 보았지만 작동했지만 누적 합계가 5 개 레코드 인 반면 5 개 레코드는 총계 만 필요했습니다. 어떤 도움? 당신의 요약 변수에

Answer 1

는에 변수 표현을 설정하려고 :

$V{REPORT_COUNT} <= 5 ? $F{my_value} : 0 

과 합계로 계산을 설정합니다. 내 그루비가 약간 녹슨처럼 죄송합니다
