Als Folgefrage zu meiner letzten Frage. Wenn ich die folgende Grafik hätte:
\documentclass{article}
\usepackage{graphicx} % Required for inserting images
\usepackage{tikz}
\usetikzlibrary{positioning}
\usepackage[margin=2.625cm]{geometry}
\usepackage{subcaption}
\begin{document}
\begin{tikzpicture}
\fill (1.5,1.5) circle [radius=0.05] node[above, yshift=-0.03cm, font=\small]{2} ;
\draw[<-, line width=0.3pt, >=stealth] (0.7,0.0) -- (1.5,1.5) node[xshift=-0.4cm,
yshift=-0.5cm, font=\tiny]{L};
\draw[<-, line width=0.3pt, >=stealth] (1.5,1) -- (1.5,1.5) node[xshift=0.4cm, yshift=-0.13cm,

\draw[<-, line width=0.3pt, >=stealth] (2.3,0.0) -- (2.3,1) node[xshift=0.1cm, yshift=-0.4cm, font=\tiny]{L};
\draw[<-, line width=0.3pt, >=stealth] (1.5,1.5) -- (2.3,1) node[above, xshift=-0.9cm, yshift=0cm, font=\tiny]{R};
\fill (1.5,0.5) circle [radius=0.05] node[above, xshift=0.1cm, yshift=-0.03cm, font=\small]{5};
\draw[<-, line width=0.3pt, >=stealth] (0.7,0)-- (1.5,0.5) node[xshift=-0.3cm, yshift=-0.05cm, font=\tiny]{L};

\end{tikzpicture}
\end{document}
Wie setze ich das „L“ und das „R“ genau in die Mitte der Zeile? Es ist wirklich mühsam, dies mit der X- und Y-Shift-Taste zu versuchen.
Antwort1
Sie müssen den Knoten auf dem Pfad angeben und nicht am Ende. Ich habe für die geneigten Verbindungen „auf halbem Weg“ und „abgeschrägt“ hinzugefügt.
Ich lasse Sie diesen Code verbessern
