如何放置内联两个图表

我有两个并排的图表，但当我添加 \caption{此处添加一些标题文本} 时，第二个图表会移到下一行。如何解决？

\documentclass{book}
\usepackage{pgfplots}
\pgfplotsset{compat=1.14}
\usepackage{tikz}
\usepackage{float}
\begin{document}

\begin{minipage}[t]{0.5\textwidth}
\begin{figure}[H]
\begin{tikzpicture}
\begin{axis}[
  xlabel=$t$,
  ylabel=$x(t)$,
  grid=major,
  %step=1cm,
  xmin=-5, xmax=5,
  ymin=-2, ymax=2,
  height=70mm, width=80mm,
  samples=99
  ]
 \addplot[red, thick, line width=1pt]{sin(90*x)+0.5};
\end{axis}
\end{tikzpicture}
\caption{Sinusne funcions}
\label{fig:fig1}
\end{figure}
\end{minipage}\hspace*{2pc}%Increase the space how much you like
\begin{minipage}[t]{0.5\textwidth}
\begin{figure}[H]
\begin{tikzpicture}
\begin{axis}[
  xlabel=$t$,
  ylabel=$x(t)$,
  grid=major,
  %step=1cm,
  xmin=-5, xmax=5,
  ymin=-2, ymax=2,
  height=70mm, width=80mm,
  samples=99
  ]
 \addplot[red, thick, line width=1pt]{sin(90*x)+0.5};
\end{axis}
\end{tikzpicture}
\caption{Sinusne functions}
\label{fig:fig2}
\end{figure}  
\end{minipage}

\end{document}

请尝试以下操作：

\documentclass{book}
\usepackage{pgfplots}
\pgfplotsset{compat=1.14}
\usepackage{tikz}
\usepackage{float}
\begin{document}

\begin{minipage}[t]{0.5\textwidth}
\begin{figure}[H]
\begin{tikzpicture}
\begin{axis}[
  xlabel=$t$,
  ylabel=$x(t)$,
  grid=major,
  %step=1cm,
  xmin=-5, xmax=5,
  ymin=-2, ymax=2,
  height=70mm, width=80mm,
  samples=99
  ]
 \addplot[red, thick, line width=1pt]{sin(90*x)+0.5};
\end{axis}
\end{tikzpicture}
\caption{Sinusne funcions}
\label{fig:fig1}
\end{figure}
\end{minipage}\hspace*{2pc}%Increase the space how much you like
\begin{minipage}[t]{0.5\textwidth}
\begin{figure}[H]
\begin{tikzpicture}
\begin{axis}[
  xlabel=$t$,
  ylabel=$x(t)$,
  grid=major,
  %step=1cm,
  xmin=-5, xmax=5,
  ymin=-2, ymax=2,
  height=70mm, width=80mm,
  samples=99
  ]
 \addplot[red, thick, line width=1pt]{sin(90*x)+0.5};
\end{axis}
\end{tikzpicture}
\caption{Sinusne functions}
\label{fig:fig2}
\end{figure}  
\end{minipage}

\end{document}

只需反转图形和小页面的顺序即可。然后您要做的就是缩小 tikzpictures，直到它们真正适合小页面。

\documentclass{book}
\usepackage{pgfplots}
\pgfplotsset{compat=1.14}
\usepackage{tikz}
\usepackage{float}
\usepackage{showframe}% MWE only
\begin{document}

\begin{figure}[H]
\begin{minipage}[t]{0.5\textwidth}
\begin{tikzpicture}
\begin{axis}[
  xlabel=$t$,
  ylabel=$x(t)$,
  grid=major,
  %step=1cm,
  xmin=-5, xmax=5,
  ymin=-2, ymax=2,
  height=70mm, width=80mm,
  samples=99
  ]
 \addplot[red, thick, line width=1pt]{sin(90*x)+0.5};
\end{axis}
\end{tikzpicture}
\caption{Sinusne funcions}
\label{fig:fig1}
\end{minipage}\hfil
\begin{minipage}[t]{0.5\textwidth}
\begin{tikzpicture}
\begin{axis}[
  xlabel=$t$,
  ylabel=$x(t)$,
  grid=major,
  %step=1cm,
  xmin=-5, xmax=5,
  ymin=-2, ymax=2,
  height=70mm, width=80mm,
  samples=99
  ]
 \addplot[red, thick, line width=1pt]{sin(90*x)+0.5};
\end{axis}
\end{tikzpicture}
\caption{Sinusne functions}
\label{fig:fig2}
\end{minipage}
\end{figure}

\end{document}
