편집 가능한 주석

이 페이지에서는 FlexChart에 주석을 표시하고 편집하는 방법을 보여 줍니다.

이 샘플에서 지원되는 주석 편집 작업은 다음과 같습니다.

  • 차트 왼쪽 위에 있는 버튼을 클릭하여 미리 정의된 주석 유형과 스타일 중 하나를 선택할 수 있습니다. 그런 다음, 차트의 plot 영역을 클릭하여 주석을 추가하고 크기를 조정합니다.
  • 데이터 좌표 버튼(맨 왼쪽)을 클릭하여 추가한 주석의 첨부 파일을 Absolute와 DataCoordinate 중에서 선택할 수 있습니다.
  • 새 버튼을 추가하여 새 주석 유형과 스타일을 코드로 만들 수 있습니다(노란색 삼각형 버튼은 사용자 정의 버튼이며 수동으로 추가된 것임).
  • 차트에서 주석을 끌 수 있습니다.
  • 주석을 두 번 클릭하여 텍스트를 편집할 수 있습니다.
  • 'x' 버튼을 사용하여 주석을 삭제할 수 있습니다.
