echarts 대시보드 설정 그래픽 예시

차트 차트는 다양한 의미를 식별하기 위해 다양한 색상에 대한 범례를 설정해야 하는 경우가 많으며, 대시보드의 포인터에는 하나의 값만 있습니다. 공식 웹사이트 구성 항목에서는 이 기능을 제공하지 않습니다. 다른 세그먼트에 대해

axisLine->lineStyle->color;를 통해 설정됩니다. 많은 정보를 검색했지만 각 색상 세그먼트를 식별하는 데 사용되는 범례를 찾을 수 없습니다. 계속해서 범례를 사용할 수 있나요? 범례를 그림에 강제로 추가하려면 어떻게 해야 하나요?

여기에서 전자 차트에 익숙한 아이들은 해결책을 생각해 냈을 것입니다.

그런 다음 "꽃 옮기기 및 아이디어 접목" 트릭을 사용해 보겠습니다.

주요 아이디어: 히스토그램의 전설을 사용하세요. 그런 다음 히스토그램 및 기기 그래프 수준을 설정한 다음 히스토그램을 숨기고 범례의 클릭 이벤트를 비활성화합니다.

참고:

　1.series에는 '유형의 구성 항목이 모두 있습니다. 게이지' 및 '바' 구성 항목을 입력하고 '바' 유형 구성 항목은 범례의 색상에만 주의하면 됩니다

　　2. 히스토그램에 숨겨야 할 항목이 많이 있으며, 축 및 구분선 등을 포함하여 모두 표시되지 않도록 설정해야 합니다.

　　3. 이상한 경험을 방지하려면 범례의 클릭 이벤트를 비활성화하는 것이 가장 좋습니다.
