Tikz: Multi-line text in the node description [duplicate]

Question

I use tikz to create pictures in latex. My picture consists of set of nodes. Every node has its own text inside the node, for example, "This node is valuable":

  \node (mynode) [mystyle,right=of anothernode] {This node is valuable};     

When I compile the document I see the description as one line.

This node is valuable

Is it possible to split the line into multiple lines? Like this:

This node

is

valuable

Which commands should one apply in order to achieve this?

Answer 1

A short example derived from the pgf/tikZ 2.10 manual.

\documentclass{minimal}
\usepackage{tikz}
\usetikzlibrary{automata,positioning}

\begin{document}
  \begin{tikzpicture}[%
    >=stealth,
    node distance=3cm,
    on grid,
    auto
  ]
    \node[state] (A)              {A};
    \node        (B) [right of=A,fill=blue!25,text width=3cm]{This is a demonstration text for showing how line breaking works.};;
    \path[->] (A) edge (B);
  \end{tikzpicture}
\end{document}

For text alignment there is also the align option.

Answer 2

Yes, you can have more than one node part (for more information, refer to the TikZ manual 48.6, p. 447, pgf/tikz 2.10).

A simple example would be like this:

\documentclass{article}

\usepackage{tikz}
\usetikzlibrary{shapes.multipart}

\begin{document}

\begin{tikzpicture}[every text node part/.style={align=center}]
\node (test) [rectangle, draw] {this node \\ has \\ four \\lines};
\end{tikzpicture}

\end{document}

Answer 3

You can just put a simple tabular environment, if you want to control the break. For instance, use

\node (mynode) [mystyle,right=of anothernode] {\begin{tabular}{c} This node \\ is \\ valuable \end{tabular}};
