在繪製的圖片下方新增標題

Question

我有以下程式碼，可以產生一個帶有箭頭的 3x3 網格。一些網格單元格中有#。

\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}

我想在繪製的圖片下方添加標題。我怎樣才能做到這一點？我相信你不能在裡面添加標題\開始{圖片}。我也嘗試將它包裹在一個\開始{圖}沒有成功。

Answer 1

把picture裡面的一個minipage.這將允許它包含在figure環境中，從而允許\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}

根據OP的評論，為了在一行上獲取多個圖像，可以將相鄰的minipages 放在同一行上，只要它們不超過\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}

你說的圖片邊界框太大了；此外，您忘記了空框的空參數。注意\Large 不爭論一下。

\documentclass{article}
\usepackage{pict2e}

\begin{document}

\begin{figure}
\centering

\begin{picture}(90,90)
\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}

\caption{A picture}

\end{figure}

\end{document}

多張圖片沒有問題：

\documentclass{article}
\usepackage{pict2e}

\begin{document}

\begin{figure}
\centering

\begin{picture}(90,90)
\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}\qquad
\begin{picture}(90,90)
\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}

\caption{A picture}

\end{figure}

\end{document}

繪製圖片的更好方法是使用線條而不是方框：這可以避免內部線條的「重複」。

\documentclass{article}
\usepackage{pict2e}

\begin{document}

\begin{figure}
\centering

\begin{picture}(90,90)
\polygon(0,0)(90,0)(90,90)(0,90)
\put(30,0){\line(0,1){90}}
\put(60,0){\line(0,1){90}}
\put(0,30){\line(1,0){90}}
\put(0,60){\line(1,0){90}}
\put(15,75){\makebox(0,0){\Large\#}}
\put(45,75){\makebox(0,0){\Large\#}}
\put(75,75){\makebox(0,0){\Large\#}}
\put(75,45){\makebox(0,0){\Large\#}}
\put(15,45){\vector(1,0){30}}
\end{picture}

\caption{A picture}

\end{figure}

\end{document}

請注意如何使用 繪製邊框\polygon。

Answer 3

這個問題很老了，但我想展示以下內容的力量和簡易tikz：

\documentclass{article}
\usepackage{tikz}
\begin{document}

\begin{figure}
\centering
\begin{tikzpicture}

\foreach \x in {0,1,2,3}
\draw (\x,0)--(\x,3)  (0,\x)--(3,\x);

\foreach \x/\y in {0.5/2.5,1.5/2.5,2.5/2.5,2.5/1.5}
\node at (\x,\y) {\Large{\#}};

\draw[-latex] (.5,1.5)--(1.5,1.5);

\end{tikzpicture}
\caption{A picture}
\end{figure}

\end{document}
