I apologize if this is a duplicate, but I'm having a hard time finding an elegant solution. I have something that "works," but feels wonky.
I'm making a presentation in beamer and I want to have boxes with arrows pointing back and forth between objects. Here's a mwe with an idea of what I would like to achieve:
\documentclass{beamer}
\usepackage{tikz}
\usetikzlibrary{calc,arrows,shapes}
\begin{document}
\begin{frame}
\tikzstyle{service} = [draw, fill=blue!20]
\begin{figure}
\begin{tikzpicture}[node distance=2cm, auto,>=latex', thick]
\path[->] node[service] (svc1) {service 1};
\path[->] node[service, right of=svc1,xshift=2cm] (svc2) {service 2}
(svc1.10) edge node {restarts} (svc2.170);
\path[->] node[service, below of=svc2] (svc3) {service 3}
(svc2.280) edge node {configures} (svc3.80);
\path[<-] (svc2.240) edge node {} (svc3.120);
\path[<-] (svc1.-10) edge node {} (svc2.190);
\end{tikzpicture}
\end{figure}
\end{frame}
\end{document}
However, I believe that this seems like such a simple problem that a more elegant (automated) solution vs. putting in angles must exist.
