Ich möchte eine halbgestrichelte Linie zeichnen, beispielsweise zwischen den Knoten X_1 und Y_{13}. Wie mache ich das?
Antwort1
Eine andere Interpretation von „halb gestrichelt“:
\documentclass[tikz,border=5]{standalone}
\usetikzlibrary{decorations.pathreplacing,calc}
\tikzset{draw half paths/.style 2 args={%
decoration={show path construction,
lineto code={
\draw [#1] (\tikzinputsegmentfirst) --
($(\tikzinputsegmentfirst)!0.5!(\tikzinputsegmentlast)$);
\draw [#2] ($(\tikzinputsegmentfirst)!0.5!(\tikzinputsegmentlast)$)
-- (\tikzinputsegmentlast);
}
}, decorate
}}
\begin{document}
\begin{tikzpicture}[every node/.style={circle, draw}, >=stealth]
\foreach \i in {1,...,5}
\node (n-\i) at (72*\i:2) {\i};
\path [draw half paths={solid}{dashed}] (n-1) -- (n-3);
\path [draw half paths={dotted}{dashed}] (n-2) -- (n-4);
\path [draw half paths={blue, thin}{red, very thick}] (n-3) -- (n-5);
\path [draw half paths={dashed}{draw=none}] (n-4) -- (n-1);
\path [draw half paths={dotted, ->}{draw=none}] (n-5) -- (n-2);
\end{tikzpicture}
\end{document}
Antwort2
Ich bin nicht ganz sicher, was Sie an der „halb gestrichelten Linie“ stört ... Wenn sie aus zwei Linien besteht, einer durchgezogenen und einer (in geringem Abstand von der durchgezogenen) gestrichelten, prüfen Sie, ob Ihr Problem dadurch gelöst wird:
\begin{scope}[on background layer]
% half dashed line
\draw (n1) -- (n13);
\draw[dashed] ($(n1)!2pt!90:(n13)$) edge ($(n13)!2pt!-90:(n1)$);
\end{scope}
Dieser Zusatz ergibt:
Dieses Bild habe ich mit MWE erstellt und es unterscheidet sich, hm, sehr von Deinem ...
