captionsfloatsindentation
Figure captions seem to wrap at the page width. How could I make them wrap at the figure width instead? Currently, they can easily be mistaken for normal text.
\begin{figure}[!htb]
\begin{center
\begin{tikzpicture} ... \end{tikzpicture}
\caption{Caption goes here.}
\end{center}
\end{figure}
Use the caption package.
\documentclass{article}
\usepackage[justification=centering]{caption}% or e.g. [format=hang]
\begin{document}
\begin{figure}
\centering
\rule{1cm}{1cm}
\caption{This caption is very long---in fact, it is so long that it doesn't fit on one line}
\end{figure}
\end{document}
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]
\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}
\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}
Best Answer
The caption package provides many enhancements: for example
Reducing the caption to the figure width seems not a good idea in general, particularly if a couple of figures are on the same page or on facing pages. On the other hand reducing the width and maybe the font size can be a good typographical device to isolate them better from the context.
