나는 이 곡선을 보간하려고 시도했지만 내가 얻은 결과는 그리 좋지 않았습니다.

결과 :
곡선이 더욱 실제처럼 보이도록 하려면 어떻게 해야 합니까? 그리고 동그라미 안의 숫자도 추가하고 싶습니다.
답변1
이를 수행하는 방법은 다음과 같습니다. 열쇠:
- 예제에서 불필요한 코드 제거
--다음으로 대체to[out=,in=]- 파란색 곡선의 중간점을 지정합니다.
- 이동하기 위해 몇 가지 변형을 사용하여 각 곡선의 끝에 레이블을 배치합니다.
controls베지어 곡선을 통한 다른 접근 방식인 을 사용할 수도 있습니다 . 시각화하기가 더 쉬워지는 효과를 발견했습니다 to.
standalone클래스를 사용 하고 패키지를 통해 해당 PDF를 포함하여 별도의 파일로 그래픽을 그리는 것이 좋습니다 graphicx. 여기를 참조하세요한 가지 예, 내가 그렇게 하자고 제안했지만여러 번 (더 찾아보세요).
