两个相邻的图形（Tikz）

Question

我读过几个与我的问题非常接近的问题，但我不知道如何将它们合并到我的代码中。我有两个图，我想将它们并排显示。你能帮我一下吗？谢谢

\documentclass{article}

\usepackage{pgfplots}
\usepackage{tikz}
\usetikzlibrary{patterns}

\pgfplotsset{compat=1.11,
/pgfplots/ybar legend/.style={
/pgfplots/legend image code/.code={%
   \draw[##1,/tikz/.cd,yshift=-0.25em]
    (0cm,0cm) rectangle (3pt,0.8em);},
},
}

\begin{document}

\pgfplotstableread[row sep=\\,col sep=&]{
interval & Eval & Dev \\
Mono     & 19.29  & 31.31 \\
Tri1     & 9.56 & 15.97  \\
Tri2    & 8.16 & 13.86 \\
Tri3   & 10 & 10 \\
}\mydata

\begin{tikzpicture}
\begin{axis}[
        ybar,
        bar width=.8cm, %ancho barra
        width=9cm, %dimensiones de figura
        height=.5\textwidth,
        legend style={at={(1,1)},
            anchor=north east,legend columns=-1},
        symbolic x coords={Mono, Tri1, Tri2, Tri3},
        xtick=data,
        nodes near coords, %letricas arriba
        nodes near coords align={vertical},
        ymin=0,ymax=35,
        ylabel={WER (\%)},
    ]
    \addplot [draw=black, fill=black] table[x=interval,y=Eval]{\mydata};
    \addplot [draw=black, pattern color = black, pattern = north west lines] table[x=interval,y=Dev]{\mydata};
    \legend{Eval, Dev}
\end{axis}
\node[above,font=\large\bfseries] at (current bounding box.north) {EN - Tg};
\end{tikzpicture}

\pgfplotstableread[row sep=\\,col sep=&]{
interval & Eval & Dev \\
Mono     & 20.87  & 32.70 \\
Tri1     & 10.22 & 16.26  \\
Tri2    & 8.38 & 14.87 \\
Tri3   & 10 & 10 \\
}\mydata

        ylabel={WER (\%)},
    ]
    \addplot [draw=black, fill=black] table[x=interval,y=Eval]{\mydata};
    \addplot [draw=black, pattern color = black, pattern = north west lines] table[x=interval,y=Dev]{\mydata};
    \legend{Eval, Dev}
\end{axis}

Answer 1

• 基于文字置于图下而不是图上和在 LaTeX 中手动放置图形（此处：章节/部分末尾）。
• 我把你的pgfplots东西放在外部文件中，以使代码结构更清晰（在我看来这是一个好主意）。
• 在这里我使用float包来手动将浮动（\begin{figure}[H]）放置在特定位置（有意见反对该解决方案）。
• 您有一个奇怪的绝对尺寸和相对尺寸混合（例如bar width=.8cm和height=.5\textwidth）。我没有优化它 - 我只是做了一些修改，直到 MWE 还可以。
• 我还展示了如何引用图形（\ref和\label）。

主要代码

\usepackage{subcaption}是必不可少的。

\begin{figure}[H]
    \centering
    \begin{subfigure}[t]{0.5\textwidth}
        \centering
        \input{pgfplots__Diagram__1.tex}
        \caption{Subcaption of the left diagram.}
        \label{Fig:SubLeft}
    \end{subfigure}%
    ~ 
    \begin{subfigure}[t]{0.5\textwidth}
        \centering
        \input{pgfplots__Diagram__2.tex}
        \caption{Subcaption of the right diagram.}
        \label{Fig:SubRight}
    \end{subfigure}
    \caption{Caption of both diagrams.}
    \label{Fig:Main}
\end{figure}
