내 트리의 요소를 범례에 추가하고 싶습니다(설명은 범례 참조). 나는 찾았다이것그리고이것대답하지만 범례에 다른 모양을 추가하는 방법은 설명하지 않습니다. pgfplots-docs에서 도움이 되는 내용을 찾지 못했습니다. 나는 범례에 대해 pgfplots에만 국한되지 않습니다. 다른 솔루션이 있으면 기꺼이 사용하겠습니다.

답변1
현재 스타일과 유사한 범례의 모양에 대한 스타일을 추가할 수 있습니다 number in legend(예: ) shape in legend. 를 사용하여 모양과 색상이라는 두 가지 인수를 허용하도록 모양 스타일을 정의할 수 있습니다 .style 2 args. 이것은 다음과 같이 호출됩니다 shape in legend={arg1}{arg2}(참조pgfplots를 사용하여 여러 필터의 데이터를 그리는 방법). 스타일 자체는 모양과 채우기 색상을 인수로 사용하는 일반 노드를 그립니다.
