How to add a node in the middle of the line with tikz?

Question

How do I add in the middle of the line a node with Tikz? I want somethink like this:

-------------->
     text

Normally I did it with an additional node at command. If I will resize the the arrow then I need to change the position of the node also.

---------->
   text

Which is not the best way for big things. I try to find something in the manual and didn't find an answer yet.

Thanks.

Best regards.

Answer 1

You could also use the midway-option

\documentclass{minimal}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
    \draw [->] (0,0) -- (5,0) node [midway, below] {Text};
    \draw [->] (0,1) -- (5,1) node [near end, below] {Text};
    \draw [->] (0,2) -- (5,2) node [pos=0.62, below] {Text};
    \draw [->] (0,3) -- (5,3) node [pos=0.2, below] {Text};
\end{tikzpicture}
\end{document}

gives

See the tikz manual section 16.8 “Placing Nodes on a Line or Curve Explicitly” …

Answer 2

You can use the node construct without the at specifier:

\documentclass{article}
\usepackage{tikz}

\begin{document}

\begin{tikzpicture}
  \draw[->] (0,0) --  node[label= below:text] {} (2,0);
  \draw[->] (0,1) --  node[label= below:text] {} (3,1);
\end{tikzpicture}

\end{document}
