차트 기능을 사용하려면 SpreadJS Chart JS 파일 링크를 문서의 헤더 섹션에 추가하십시오.
아래와 같이 sheet.charts.add 메서드로 차트를 만들 수 있습니다.
또한 차트의 데이터 소스가 다중 선택된 항목임을 지정할 수도 있습니다.
설정된 데이터 소스가 표 구조 참조와 같을 경우 차트는 자동으로 계열 영역을 업데이트합니다.
sheet.charts.get 메서드를 사용하여 시트에서 차트를 가져오거나, sheet.charts.remove 메서드를 사용하여 차트를 제거하거나, sheet.charts.clear 메서드를 사용하여 모든 차트를 지울 수 있습니다.
차트는 여러 하위 요소로 작성되며 차트 API를 사용하여 각 하위 요소를 사용자 정의할 수 있습니다.
차트 제목: 차트의 제목
차트 제목의 텍스트, 배경색, 전경색, 글꼴 및 글꼴 크기를 가져오거나 설정할 수 있습니다.
계열: 차트에 그려지는 데이터 계열의 데이터 요소
차트의 계열 컬렉션에서 계열 항목을 가져오거나 추가하거나 제거할 수 있을 뿐만 아니라, 각 계열 항목의 이름, 테두리, 너비, 테두리 색, y 값, x 값 및 채우기 색을 사용자 정의할 수 있습니다.
데이터 레이블: 데이터 레이블을 사용하여 데이터 계열에서 데이터 요소의 세부 사항을 식별할 수 있습니다.
아래 옵션 중에서 차트의 계열 데이터 레이블 스타일을 사용자 정의할 수 있습니다.
showValue
showSeriesName
showCategoryName
showPercentage
separator
position
format
color
transparency
backColor
backColorTransparency
borderColor
borderWidth
borderColorTransparency
SpreadJS는 28가지 차트 유형을 제공합니다. 다음 코드를 사용하여 현재 차트 유형을 가져오거나 설정할 수 있습니다.
SpreadJS는 다음과 같은 방법으로 빈 셀을 표시하고 #N/A 셀을 차트에 빈 셀로 표시합니다.
간격: Null 값을 건너뜁니다.
0: Null 값을 값이 0인 것으로 간주합니다.
연결됨: Null 값을 건너뛰고 영역형 차트의 선이 연결됩니다.
SpreadJS는 차트의 숨겨진 행과 열을 표시하거나 무시하는 기능을 지원합니다.
SpreadJS는 가져오기 중에 지원되지 않는 차트 유형을 유지하거나 무시하는 기능을 지원합니다.
