label overlapping with arrow in tikz

Question

First, the working code:

\documentclass[journal]{IEEEtran}
\usepackage{libertine}
\usepackage{cite}
\usepackage{url}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amsthm}
\usepackage{mathtools}
\usepackage{setspace}
\usepackage{algorithm}
\usepackage{algorithmicx}
\usepackage{algpseudocode}
\usepackage[english]{babel}
\usepackage{tikz}
\usetikzlibrary{arrows}
\begin{document}
\begin{center}
\begin{tikzpicture}[->,>=stealth',shorten >=1pt,auto,node distance=3cm,
  thick,main node/.style={,fill=white!20,draw,font=\sffamily\small\bfseries}]

  \node[main node] (dancing) {dancing};
  \node[main node] (monkey) [below of=dancing] {monkey};

\path[every node/.style={font=\sffamily\small}]
    (dancing) edge node [below] {test} (monkey)
;
\end{tikzpicture}
\end{center}
\end{document}

As shown below, I get overlapping text with the arrow.

Is there a way to change this? Can I also modify the size of the arrow for individual arrows in my graph?

Thanks a lot!

Answer 1

This is a possible solution. use rotatebox from graphicx package, or with the help from tikzlibrary postioning with above left=xxcm and xxcm or below right=xx cm and xxcm.

Code

\documentclass{article}
\usepackage{tikz,graphicx}

\usetikzlibrary{arrows,positioning,calc}
\begin{document}
\begin{tikzpicture}[->,>=stealth',shorten >=1pt,auto,node distance=3cm,
  thick,main node/.style={,fill=white!20,draw,font=\sffamily\small\bfseries}]

  \node[main node] (dancing) {dancing};
  \node[main node,below=3cm of dancing] (monkey) {monkey};

\path[]
    (dancing) edge node [] {\rotatebox[origin=cc]{90}{test}} (monkey)
;
\path[]
    (dancing) edge node [below right=0.5cm and 0.1cm] {test} (monkey)
;
\path[]
    (dancing) edge node [above left=0.5cm and 0.1cm] {test} (monkey)
;
\end{tikzpicture}

\end{document}
