如何使子标题标签出现在左上角？

目前，我正在使用此代码

\documentclass[letterpaper,12pt]{article}
\usepackage[margin=1in]{geometry} % set page parameters appropriately
\usepackage{subcaption}
\captionsetup{font={bf,small},skip=0.25\baselineskip}
\captionsetup[subfigure]{font={bf,small}, skip=1pt}


\begin{figure}[H]
\centering
\begin{subfigure}{0.49\linewidth}
\centering
\includegraphics[width=1.2\linewidth, height=0.17\textheight, keepaspectratio]{H_beffect.png}%, 
\caption{}
\label{fig:halfsaturationeffect}
\end{subfigure}
%\quad
\begin{subfigure}{0.49\linewidth}
\centering
\includegraphics[width=1.2\linewidth, height=0.17\textheight, keepaspectratio]{BIHSItransmission.png}
\caption{The effect of $\beta_b$ on $R_{ah}$}
\label{fig:rateoftransmission}
\end{subfigure}
%\hfill
\caption{Effect of half-saturation constant for birds with avian strain and transmission coefficient on the basic reproduction number.}
\label{fig:effectonR_0}
\end{figure}

我怎样才能使子图标题位于每个子图的左上角而不是子图下方？

像这样？

在此处输入图片描述

关于主题：

  • 只是放在\caption{...}之前includegraphics
  • 加上\captionsetup[subfigure]{...}​singlelinecheck=false

无关：

  • 您的代码中缺少\begin{document}，end{document}并且包graphicx
  • 不要使用figure选项[H]，它可能会导致不愉快的文档格式。该选项[ht]应该足够了
  • 不要强制图像的宽度大于subfigure环境的宽度（图像会重叠）

\documentclass[letterpaper,12pt]{article}
\usepackage[margin=1in]{geometry} % set page parameters appropriately
\usepackage[demo]{graphicx}
\usepackage{subcaption}
\captionsetup{font={bf,small},skip=0.25\baselineskip}
\captionsetup[subfigure]{font={bf,small}, skip=1pt, singlelinecheck=false}

\begin{document}
\begin{figure}
\centering
\begin{subfigure}{0.49\linewidth}
\caption{}
\label{fig:halfsaturationeffect}
    \includegraphics[width=\linewidth, height=0.17\textheight, keepaspectratio]{H_beffect.png}%,
\end{subfigure}
\hfill
\begin{subfigure}{0.49\linewidth}
\caption{The effect of $\beta_b$ on $R_{ah}$}
\label{fig:rateoftransmission}
    \includegraphics[width=\linewidth, height=0.17\textheight, keepaspectratio]{BIHSItransmission.png}
\end{subfigure}
\caption{Effect of half-saturation constant for birds with avian strain and transmission coefficient on the basic reproduction number.}
\label{fig:effectonR_0}
\end{figure}
\end{document}
