LaTeX에서 노모그램을 어떻게 그릴 수 있나요?

노모그램이란 무엇입니까?

"ㅏ노모그램노모그래프, 정렬 차트 또는 아바크라고도 불리는 는 그래픽 계산 장치로, 함수의 대략적인 그래픽 계산을 허용하도록 설계된 2차원 다이어그램입니다.

예

이 노모그램 상단에 제시된 로켓 방정식은 왼쪽 눈금에서 오른쪽 눈금까지 선을 그리면 풀 수 있습니다. 용액은 중앙의 눈금에서 읽을 수 있습니다.

로켓 방정식의 노모그램

질문

LaTeX에서 위 그림을 어떻게 재현할 수 있나요? TikZ 접근 방식이 있습니까?

보너스 질문

LaTeX로 임의의 노모그램을 어떻게 만들 수 있나요?

추가 정보

위 그림은 다음을 사용하여 생성되었습니다.http://pynomo.org/wiki/index.php?title=Main_Page

답변1

부인 성명

이를 시작점으로 삼아 솔루션이 모든 경우에 실제로 작동하도록 하려면 수행해야 할 몇 가지 작업이 있습니다. 즉:

  • 나머지(최대/최소)!=0인 경우를 처리합니다.
  • 최소 처리!=0
  • 최소에서 최대까지 외에 최대에서 최소까지 규모를 처리합니다.

가능성:

답변2

를 사용한 계산의 정밀도 문제로 인해 TikZ접근 방식을 변경하고 작은 pearl스크립트를 사용하여 이 계산을 수행했습니다. 다음으로 실행pdflatex -shell-script

나는 decorations.markings모든 유형의 경로에서 졸업을 하기 위해 도서관을 사용합니다. (더 이상 점수 문제가 누적되지 않습니다).

코드에 몇 가지 설명을 넣으려고 했습니다.
