원형 차트를 Spread에 추가할 수 있으며 차트 스타일은 차트 API를 사용하여 변경할 수 있습니다. 원형 차트는 하나의 데이터 그룹만 표시할 수 있으므로 chart.series().get() 함수를 사용하여 계열 정보를 가져옵니다. 원형 차트는 하나의 데이터 계열에 있는 항목의 크기를 표시하고 데이터 요소는 전체 원형의 백분율로 표시됩니다.
도넛형 차트를 Spread에 추가할 수 있으며 차트 스타일은 차트 API를 사용하여 변경할 수 있습니다. 도넛형 차트는 모든 계열을 표시할 수 있으며 각 계열은 데이터 계열을 나타내는 고리로 표시됩니다.
