# How to make the arrow head still look nice for a short curved path?

\documentclass[pstricks,border=12pt]{standalone}
\usepackage{pst-node,multido}
\psset{arcangle=90,nodesep=3pt,arrows=->}
\begin{document}
\multido{\n=3+-.75}{4}{%
\pspicture(3,3)
\rput[bl](0,1){\rnode[t]{A}{A}}
\rput[br](\n,1){\rnode[t]{B}{B}}
\ncarc{A}{B}
\endpspicture}
\end{document}


• Using a Computer Modern style arrow could help. – egreg Oct 26 '13 at 20:36
• change the arcangle for each iteration. Don't arrive at the second node 90 degrees always. – percusse Oct 27 '13 at 1:21

Just for fun, with TikZ and the new CVS bending library:

\documentclass[border=0.125cm]{standalone}
\usepackage{tikz}
\usetikzlibrary{arrows.meta,bending}
\begin{document}

\begin{tikzpicture}

\tikzset{>=Stealth}
\node at (0.5,1) {Normal};
\node (A) {A};
\node (B) at (1 ,0) {B};
\draw [<->] (A.north) .. controls ++(0,0.25) and ++(0,0.25) .. (B.north);

\tikzset{xshift=2cm, >={Stealth[bend]}}
\node at (0.5,1) {Bent};
\node (A) {A};
\node (B) at (1 ,0) {B};
\draw [<->] (A.north) .. controls ++(0,0.25) and ++(0,0.25) .. (B.north);

\end{tikzpicture}

\end{document}


• that is not the same, your start and end angles are not 90 degrees – user2478 Oct 29 '13 at 13:36
• @Herbert the start and end angles for the path are now 90 degrees. The adjustments to the path and arrow tip angle are computed by the library. – Mark Wibrow Oct 29 '13 at 13:47
• I see, you are right – user2478 Oct 29 '13 at 14:10
