[Tex/LaTex] Put a caption under a drawn picture

captionsdiagramsfloats

I have the following code that produce a 3×3 grid with an arrow in it. Some of the grid cells have a # in them.

\begin{picture}(185,90)
\put(0,0){\framebox(30,30)}
\put(30,0){\framebox(30,30)}
\put(60,0){\framebox(30,30)}
\put(0,30){\framebox(30,30)}
\put(30,30){\framebox(30,30)}
\put(60,30){\framebox(30,30){\Large{\#}}}
\put(0,60){\framebox(30,30){\Large{\#}}}
\put(30,60){\framebox(30,30){\Large{\#}}}
\put(60,60){\framebox(30,30){\Large{\#}}}
\put(15,45){\vector(1,0){30}}
\end{picture}

Result produce with pdflatex

I would like to put a caption under the drawn picture. How could I achieve this? I believe that you can't put a caption inside a \begin{picture}. I have also try to wrap it inside a \begin{figure} without success.

Put the picture inside a minipage. This will allow it to be included in a figure environment, which will therefore allow a \caption.

\documentclass{article}
\usepackage{lipsum}
\begin{document}
\lipsum[1]
\begin{figure}[ht]
\centering
\begin{minipage}{1.3in}
\begin{picture}(185,90)
\put(0,0){\framebox(30,30)}
\put(30,0){\framebox(30,30)}
\put(60,0){\framebox(30,30)}
\put(0,30){\framebox(30,30)}
\put(30,30){\framebox(30,30)}
\put(60,30){\framebox(30,30){\Large{\#}}}
\put(0,60){\framebox(30,30){\Large{\#}}}
\put(30,60){\framebox(30,30){\Large{\#}}}
\put(60,60){\framebox(30,30){\Large{\#}}}
\put(15,45){\vector(1,0){30}}
\end{picture}
\end{minipage}
\caption{Here is my caption.}
\end{figure}
\lipsum[2]
\end{document}

Following up on the OP's comment, one can, in order to get multiple images on a single line, place adjacent minipages on the same line, as long as they don't exceed the \linewidth.

\documentclass{article}
\usepackage{lipsum}
\begin{document}
\lipsum[1]
\begin{figure}[ht]

\begin{minipage}{1.3in}

\put(0,0){\framebox(30,30)}
\put(30,0){\framebox(30,30)}
\put(60,0){\framebox(30,30)}
\put(0,30){\framebox(30,30)}
\put(30,30){\framebox(30,30)}
\put(60,30){\framebox(30,30){\Large{\#}}}
\put(0,60){\framebox(30,30){\Large{\#}}}
\put(30,60){\framebox(30,30){\Large{\#}}}
\put(60,60){\framebox(30,30){\Large{\#}}}
\put(15,45){\vector(1,0){30}}
\end{picture}
\end{minipage}
\begin{minipage}{1.3in}

\put(0,30){\framebox(30,30)}

Since this seems like an out-of-the-ordinary setting for a figure, it may require some manual fiddling. The following example sets a list-like environment containing the "figure", and it allows your caption to break across the page boundary.

enter image description here

\documentclass{scrartcl}
\usepackage{graphicx,lipsum,afterpage,subcaption}
\usepackage{enumitem}
\begin{document}

\lipsum[1-5]

\makeatletter
\afterpage{\begin{center}
    \def\@captype{figure}% Fake a figure environment
    \subcaptionbox{Sub1}{\includegraphics[width=.2\linewidth]{example-image-a}} \qquad
    \subcaptionbox{Sub2}{\includegraphics[width=.2\linewidth]{example-image-a}} \qquad
    \subcaptionbox{Sub3}{\includegraphics[width=.2\linewidth]{example-image-a}} \par\bigskip
    \subcaptionbox{Sub4}{\includegraphics[width=.2\linewidth]{example-image-a}} \qquad
    \subcaptionbox{Sub5}{\includegraphics[width=.2\linewidth]{example-image-a}} \qquad
    \subcaptionbox{Sub6}{\includegraphics[width=.2\linewidth]{example-image-a}}
  \end{center}
  \addcontentsline{lof}{figure}{\protect\numberline{\thefigure}A length figure}% LoF entry
  \settowidth{\@tempdima}{Figure~\thefigure: }%
  \begin{itemize}[labelindent=\parindent,labelwidth=\@tempdima,rightmargin=\parindent,leftmargin=\dimexpr\@tempdima+\parindent]
    \item[Figure~\thefigure:]
    \lipsum[6-10]
  \end{itemize}
}
\makeatother

\lipsum[6-12]

\end{document}

The sub-figures are set using subcaption using the regular interface inside a center environment. A faked figure is initiated by defining the caption type \@captype. Setting of the caption is inside a regular list itemize with appropriate width settings (to match your other figures).

A short LoF-entry is set manually via \addcontentsline{lof}{figure}{<short entry>}. This is displayed with the inclusion of \listoffigures.

All of the above is passed to \afterpage (supplied by afterpage) in order to provide a seemless transition from page-to-page. One may play around with the spacing following the "figure". For example, adding something like \addvspace{\textfloatsep}.

_{The page layout was added via \usepackage{showframe} in the preamble; removed in the above code.}

[Tex/LaTex] Full-page figure with preceding caption

I'd just put the caption in a [b] figure and the image in a [p] the caption figure will float until there is room for the caption at the bottom if the page, and at the following page break the pending p float will necessarily be output. (I'd never use afterpage: I know who wrote it:-)

\documentclass{article}
\usepackage{lipsum,graphicx}
\begin{document}
\lipsum[1-11]


\begin{figure}[b]
  \caption[Some rather long caption]{\lipsum*[2]}
\end{figure}
\begin{figure}[p]
    \includegraphics[width=\textwidth,height=.999\textheight]{example-image}% La
\end{figure}
\lipsum[12-20]
\end{document}
