图 4.1 是两个子图,每个子图都有一个标题(技术上总共有四个图,但行上的图是一张图片)。
使用
\documentclass[twocolumn,titlepage]{report}
\usepackage{verbatim}
\usepackage{amsfonts}
\usepackage{amsmath}
%%\usepackage{subfigure}
\usepackage{amssymb}
\usepackage[pdftex]{graphicx}
\usepackage{geometry}
\usepackage{titlesec}
\usepackage[center]{caption}
\usepackage{subcaption}
\titleformat{\chapter}[block]
{\normalfont\huge\bfseries}{\thechapter}{1em}{}
\geometry{
body={7in, 10in},
left=0.75in,
top=0.5in
}
\begin{document}
\begin{figure}[ht]
\begin{subfigure}[b]{0.3\textwidth}
\includegraphics[width=8.7cm]{fig5-a.png}
\caption{\textit{I-V Charactaristic at 1Hz (left) and 5 Hz (right)}}
\end{subfigure}
\begin{subfigure}[b]{0.3\textwidth}
\includegraphics[width=8.7cm]{fig8.png}
\caption{\textit{I-V Charactaristic at 10 Hz (left) and 500Hz (right)}}
\end{subfigure}
\caption{I-V Charactaristics of varying frequencies, showing the expected tightening of the bow}
\label{fig:freqdep}
\end{figure}
\end{document}
标题没有与整个图对齐。理想情况下,标题应该横跨图 4.1 a 中两个图的宽度
答案1
您已将每个子图的宽度指定为0.3\textwidth
,并设置了标题的宽度。但包含的图形要宽得多,因此会突出。
为了解决这个问题,请将子图的宽度设置为整列宽度:
\documentclass[twocolumn]{article}
\usepackage[draft]{graphicx}
\usepackage{subcaption}
\begin{document}
\begin{figure}[ht]
\begin{subfigure}[b]{\columnwidth}
\includegraphics[width=\columnwidth]{fig5-a.png}
\caption{\textit{I-V Charactaristic at 1Hz (left) and 5 Hz (right)}}
\end{subfigure}
\begin{subfigure}[b]{\columnwidth}
\includegraphics[width=\columnwidth]{fig8.png}
\caption{\textit{I-V Charactaristic at 10 Hz (left) and 500Hz (right)}}
\end{subfigure}
\caption{I-V Charactaristics of varying frequencies, showing the expected tightening of the bow}
\label{fig:freqdep}
\end{figure}
\end{document}
