Math symbols (\subseteq and \supseteq) are rotated and rendered successfully in text mode with the aid of \rotatebox{}{}.

In the commented section below, there is a problem with getting these symbols into the subfloat label. I'm using pdflatex

This is pdfTeX, Version 3.1415926-1.40.11 (Web2C 2010) Any ideas? Thanks.

\documentclass[a4paper]{article}

\usepackage{graphicx}
\usepackage{subfig}
\usepackage{tikz}
\usepackage{stmaryrd}
\usepackage{fouriernc}
\usepackage{MnSymbol}
\usepackage{colonequals}
\usepackage{ulem}
\usepackage{fancybox} 

\usetikzlibrary{arrows, shapes, patterns}
\pagestyle{myheadings}

\begin{document}
\rotatebox{90}{$\supseteq$}
\rotatebox{90}{$\subseteq$}

\begin{figure}
\centering
%\subfloat[Text $\overline{A\cup B}$,\;$\downarrow$\rotatebox{90}{$\supseteq$}]{
\subfloat[Text $\overline{A\cup B}$,\;$\downarrow$]{
 \begin{tikzpicture}[scale=0.5, auto, swap]
   \draw (-1,0) circle (1);
   \draw (2,0) circle (1);
   \node at (-2,1) [above left] {$A$};
   \node at (3,1) [above right] {$B$};
 \end{tikzpicture}
}\qquad
\caption{Sets}
\end{figure}
\end{document}

EDIT: Addition of parameter origin=c to \subfloat[Text $\overline{A\cup B}$,\;$\downarrow$\protect\rotatebox[origin=c]{-90}{$\subseteq$}]{ Without as seen in the picture.

  • What version of TeX/TikZ are you using? I seem to be getting an error on tikzlibrary. Latex Error: ./untitled2.tex:13 I can't find file `tikzlibrary'. Is it just my distribution?

  • As far as I can tell my configuration is latex2e, pdfTeX, pdflatex, Tex Live 2010...for tikz I would say the latest available version :) My error is ! Argument of \sf@@@subfloat has an extra }. <inserted text> \par l.30 } \qquad

  • Oh, my, it seems I haven't run an update in a while, so I may be a bit outdated. I'll let you know what I find out when it finishes updating.

Use \protect before \rotatebox. This prevents the early expansion of \rotatebox, see What is the difference between Fragile and Robust commands for an explanation.

\subfloat[Text $\overline{A\cup B}$,\;$\downarrow$\protect\rotatebox{90}{$\supseteq$}]{

  • How can I make \subfloat[Text $\overline{A\cup B}$,\;$\downarrow$\protect\rotatebox[origin=c]{-90}{$\subseteq$}]{ work? rotating \subseteq -90 changes symbol height or moves it vertical lower.

    @panny: it works if you define a macro: \newcommand*{\rot}{\rotatebox[origin=c]{-90}{$\subseteq$}} and protect that later in the subfloat command: ...\protect\rot.
