이동 평균

MovingAverage 클래스는 일반 Series 클래스를 확장하여 전체 데이터 집합에서 여러 다른 하위 집합의 평균 계열을 제공합니다.

차트에 이동 평균을 추가하려면 다음 단계를 수행합니다.

  1. MovingAverage 계열을 하나 이상 만듭니다.
  2. binding, chartType, style 등의 속성을 설정하여 일반 계열과 동일한 방식으로 MovingAverage 계열을 구성합니다.
  3. MovingAverage의 typeperiod 속성을 설정하여 만들려는 이동 평균의 유형을 결정합니다.
