플롯 아래 노드에 공통 범례를 배치하여 그룹 플롯을 구성 중입니다. 내 문제를 재현하는 MWE는 다음과 같습니다.

데이터는 다음에서 확인할 수 있습니다.
ElicitedFixedAlphaPlusPlus.txt
다음과 같은 출력이 생성됩니다.
마지막 두 개의 범례 항목이 누락되었다는 점을 제외하면 괜찮습니다.
그룹 플롯 정의에는
legend entries={{\tiny Hold All},{\tiny Come and Go},{\tiny Random},{\tiny +Resources},{\tiny ++Resources},{\tiny ++ResourcesPT},{\tiny ++ResourcesSM},{\tiny ++ResourcesBM}},
하지만 이미지에서 볼 수 있듯이 마지막 두 개는 없습니다. 해당 데이터 시리즈는 차트에 있습니다. 가장 오른쪽 차트에서는 모두 서로 겹쳐져 있기 때문에 보기 어렵지만 거기에 있습니다. 그렇다면 범례 항목이 표시되지 않는 이유는 무엇입니까?

파일 에서 .log경고를 찾을 수 있습니다

이것이 의미하는 바는 Fig3Legend레이블이 세 가지 모두에 적용된다는 것입니다 groupplots. 따라서 \ref이 중 마지막 것만 가리킵니다 groupplot. 플롯이 6개뿐이므로 범례에 6개의 항목이 표시됩니다. 한 가지 해결 방법이 아래에 나와 있습니다. 먼저 플롯에 대해 8가지 스타일을 정의하고(편의상 꼭 필요한 것은 아닙니다) 마지막에 범례에 추가 항목을 추가하는 데 사용되는 groupplot2개를 추가합니다 .\addlegendimage
+Resources그리고 의 스타일도 ++Resources약간 변경하여 혼동의 가능성을 줄였습니다. 같은 스타일의 세 줄이 있었습니다.
