# Label error on scope rotation

Within the provided code, I want to define a TiKz scope and to scale the contents of such scope.

\documentclass{beamer}
\usepackage{tikz}

\tikzstyle{result}[blue] = [draw=#1,rounded corners,align=center,label={north:\{User,Paper\}}]

\begin{document}
\begin{tikzpicture}
\begin{scope}[scale=0.5,every node/.style={transform shape}]
\node[result] {ciao};
\end{scope}
\end{tikzpicture}

\end{document}


By the way, I got the following error:

Package PGF Math Error: Unknown function north' (in 'north').

See the PGF Math package documentation for explanation. Type H for immediate help. ...

                                               l.9        \node[result] {ciao};


Is there a way to preserve the labels within the node transformation? Thanks in advance.

See, if the following solution work for you:

\documentclass{beamer}
\usepackage{tikz}

\begin{document}
\begin{frame}[fragile]
\begin{tikzpicture}[
result/.style = {draw=#1, rounded corners, align=center,
label=above:{\{User,Paper\}}},
result/.default = blue
]
\begin{scope}[scale=0.5,every node/.append style={transform shape}]
\node[result] {ciao};
\end{scope}
\end{tikzpicture}
\end{frame}
\end{document}


In this case you need to replace north with above (assuming, that with north you expect that label is above node). Since tikzstyle is deprecated I move node stale definition into tikzpicture` options.

• Yes, literally I just had to replace "north" with "above" in my code. Thanks for the update! – jackb Dec 24 '16 at 9:39
