# How to form braces or brackets used in math formulas around nodes in a TikZ picture? [duplicate]

Adding a large brace next to a body of text

I'm trying to create a brace or bracket around two or more nodes within a TikZ picture. Since there are more elements in the picture which are not to be encompassed by the bracket or brace, I can't use the "insert the picture into LaTeX math mode" approach.

Here's the example code, for easy copy-pasting:

\documentclass{standalone}

\usepackage{tikz}
\usetikzlibrary{shapes,arrows}
\usetikzlibrary{positioning}

\begin{document}

\begin{tikzpicture}[box/.style={rectangle, fill=black, minimum size=1cm}]
\node [box] (a) {};
\node [box, below=of a] (b) {};
\node [box, below=of b] (c) {};
\node [box, below=of c] (d) {};
\end{tikzpicture}

\end{document}

Anyway, I found how to do this in tex.stackexchange.com/questions/1559/… Don't know if this should be closed or I should put it as answer... – gablin Sep 29 '11 at 13:03
• Often how it goes. I think that for this one, I'd go for "close as duplicate". – Loop Space Sep 29 '11 at 13:27

• Sorry, I have to disagree that it's an exact duplicate, as the referenced question doesn't involve Tikz... – Brent.Longborough Sep 29 '11 at 21:18
