Calculated Field Aggregates (Angular)

PivotField 객체에는 사용자 정의 계산을 지원하는 두 가지 속성이 있습니다. getValue 속성은 데이터 항목(data item)을 매개 변수로 사용하고 데이터 항목의 다른 속성을 기반으로 계산 된 값을 반환하는 함수입니다. 이 함수는 집계(aggregate) 정보에 액세스 할 수 없습니다. 이 샘플은 getValue 함수를 사용하여 원본(Raw) 판매 값를 "높음", "중간"또는 "낮음"의 세 가지 수준으로 분류하는 Range 필드를 구현합니다.

getAggregateValue 속성은 요약 행(summary row)을 매개 변수로 사용하고 필드의 집계로 표시 할 값을 반환하는 함수입니다. 이 기능은 개별(individual)/원본(raw) 데이터 항목에 액세스 할 수 없습니다. 이 샘플은 getAggregateValue 함수를 사용하여 각 요약 행의 판매/다운로드 비율을 표시하는 Conversion 필드를 구현합니다.
