TeX - LaTeX Asked on May 9, 2021
I am wondering if there is a way to reverse the arrow tip but keep the length of the line constant? I checked the arrow.meta
documentation, but could not find something like rotate
…
MWE
documentclass[border=5pt]{standalone}
usepackage{tikz}
usetikzlibrary{arrows.meta}
begin{document}
begin{tikzpicture}
draw[orange, very thin] (0.93,-0.5) -- (0.93,1.5);
draw[orange, very thin] (1,-0.5) -- (1,1.5);
% draw[orange, very thin] (1.07,-0.5) -- (1.07,1.5);
draw[-{>[length=0.07cm]}] (0,0) -- (1,0);
draw[-{<[length=0.07cm]}] (0,0.5) -- (1,0.5);
% draw[-{>[rotate=180]}] (0,1) -- (1,1);
draw[-{<[length=0.07cm]}] (0,1) -- (1.07,1);
end{tikzpicture}
end{document}
In my example, I defined the length of the tip and added the length to the total length, but maybe there is an easier way to do it?
In addition to the great comment from Sandy G, I recommend to create a tikzset
for this, to let you use it even with predfined nodes and not having to do any calculation everytimes.
documentclass[tikz,border=3.14mm]{standalone}
usetikzlibrary{arrows.meta}
tikzset{%
revarrow/.style={-{<[length=#1]},shorten >=-#1},
circ/.style={circle,inner sep=1pt,fill=black,label={#1}}}
begin{document}
begin{tikzpicture}
path (0,0) node[circ=A](A){} --++ (3,0) node[circ=B](B){};
draw[orange,revarrow=.5cm,thick] (A.center)--(B.center);
end{tikzpicture}
end{document}
