계열 선택기

FlexChart's 차트의 series 속성, ListBox 컨트롤, Wijmo의 showPopuphidePopup 메서드를 사용하여 계열 선택기 UI를 간편하게 구현할 수 있습니다.

예를 들어 아래 차트는 자동 생성된 계열 집합으로 시작됩니다. 왼쪽 위에 있는 기어 아이콘을 클릭하여 ListBox를 표시하고, 여기서 표시하려는 계열을 선택할 수 있습니다.

차트의 legendToggle 속성을 true로 설정하여 비슷한 결과를 얻을 수도 있습니다. 이렇게 하면 범례 자체가 계열 선택기 역할을 합니다. 범례에서 계열 이름을 클릭하면 표시 여부가 토글됩니다.
