\filldraw가 채워지지 않습니다.

Question

내 논문에는 기본 색상 개념과 나침반의 유사점을 논의하는 이미지가 있습니다. 원본 이미지는 페인트로 초라하게 밀어넣은 것인데 tikz. 원본 이미지는 다음과 같습니다. 내 계획은 결국 이것과 막연하게 비슷한 것을 만드는 것이지만 지금은 검은 색으로 채우려는 영역이 채워지지 않고 내가 뭘 잘못하고 있는지 알 수 없기 때문에 막혔습니다. 현재로서는 다음과 같습니다.

나는 두 북쪽 선 사이의 영역을 검은색으로 표시하고 싶었습니다. 그리고 이것은 내 코드입니다:

내 코드가 매우 반복적이라는 것을 알고 있지만 측면을 정의하고 tikzpicture생성하려고 시도했지만 /.style성공하지 못했기 때문에 작동하도록 이 방식으로 수행하기로 결정하고 나중에 모든 작업이 완료되면 정리합니다. 세부 사항이 파악되었습니다.

노드 대신 좌표를 사용해야 합니다.
