如何使用 tikzpicture 和表格

Question

我尝试将图形垂直放置到同一个图形中。但是，我无法使用tabularwithtikzpicture来执行此操作。

\begin{figure}[]
  \begin{center}
    \begin{tikzpicture}[scale=0.9]
      \begin{axis}[
          width=\linewidth, % Scale the plot to \linewidth
          height=0.5\linewidth,
          grid style={dashed,gray!60},
          ylabel=Performance gain/drop percentage,
          yticklabel={\pgfmathprintnumber\tick\%},
          legend style={at={(1,0)},anchor=south east},
          xticklabels={,,},
          xlabel=Something
        ]
        \addplot[smooth,color=orange,mark=x,thick] 
        table[x=index,y=data,col sep=semicolon] {C2.csv};
        \addplot[smooth,color=blue,mark=*,thick] 
        table[x=index,y=data,col sep=semicolon] {C2.csv};
        \legend{Something}
      \end{axis}
    \end{tikzpicture}
    \caption{Something}
    \label{figure_2_s}
  \end{center}
\end{figure}

\begin{figure}[]
  \begin{center}
    \begin{tikzpicture}[scale=0.9]
      \begin{axis}[
          width=\linewidth, % Scale the plot to \linewidth
          height=0.5\linewidth,
          grid style={dashed,gray!60},
          ylabel=Performance gain/drop percentage,
          yticklabel={\pgfmathprintnumber\tick\%},
          legend style={at={(1,0)},anchor=south east},
          xticklabels={,,},
          xlabel=Something
        ]
        \addplot[smooth,color=orange,mark=x,thick] 
        table[x=index,y=data,col sep=semicolon] {C4.csv};
        \addplot[smooth,color=blue,mark=*,thick] 
        table[x=index,y=data,col sep=semicolon] {C4.csv};
        \addplot[smooth,color=gray,mark=o,thick] 
        table[x=index,y=data,col sep=semicolon] {C4.csv};
        \legend{Something}
      \end{axis}
    \end{tikzpicture}
    \caption{Something}
    \label{figure_4_s}
  \end{center}
\end{figure}

Answer 1

我不确定你的问题，但我知道你想要两个tikzpictures在里面figure，可能每个都有标签和标题。你可以使用subcaption包。由于你希望你的图形垂直对齐，所以不需要minipage或环境，但如果你想与主图形区分开来，subfigure你必须将每个图形包含在自己的范围内。{...}subcationscaption

\documentclass{article}
\usepackage{pgfplots}
\usepackage{subcaption}
\begin{document}

\begin{figure}[]
\centering
{%First subfigure
    \begin{tikzpicture}[scale=0.9]
      \begin{axis}[
          width=\linewidth, % Scale the plot to \linewidth
          height=0.5\linewidth,
          grid style={dashed,gray!60},
          ylabel=Performance gain/drop percentage,
          yticklabel={\pgfmathprintnumber\tick\%},
          legend style={at={(1,0)},anchor=south east},
          xticklabels={,,},
          xlabel=Something
        ]
%        \addplot[smooth,color=orange,mark=x,thick] 
%        table[x=index,y=data,col sep=semicolon] {C2.csv};
%        \addplot[smooth,color=blue,mark=*,thick] 
%        table[x=index,y=data,col sep=semicolon] {C2.csv};
        \legend{Something}
      \end{axis}
    \end{tikzpicture}
    \subcaption{First subfigure}
    \label{figure_2_s}
}

{%Second subfigure    
\begin{tikzpicture}[scale=0.9]
      \begin{axis}[
          width=\linewidth, % Scale the plot to \linewidth
          height=0.5\linewidth,
          grid style={dashed,gray!60},
          ylabel=Performance gain/drop percentage,
          yticklabel={\pgfmathprintnumber\tick\%},
          legend style={at={(1,0)},anchor=south east},
          xticklabels={,,},
          xlabel=Something
        ]
        \legend{Something}
      \end{axis}
\end{tikzpicture}

Answer 2

您不需要两个figure环境。您也不需要tabular。将两个tikzpictures 放在同一个figure环境中，并在它们之间留出一个空白行，以使它们垂直对齐。

\documentclass{article}
\usepackage{pgfplots}
\pgfplotsset{compat=1.12}
\begin{document}
  \begin{figure}[htb]
  \centering
    \begin{tikzpicture}[scale=0.9]
      \begin{axis}[
          width=\linewidth, % Scale the plot to \linewidth
          height=0.5\linewidth,
          grid style={dashed,gray!60},
          ylabel=Performance gain/drop percentage,
          yticklabel={\pgfmathprintnumber\tick\%},
          legend style={at={(1,0)},anchor=south east},
          xticklabels={,,},
          xlabel=Something
        ]
        \addplot[smooth,color=orange,mark=x,thick]
         {rnd};
        \addplot[smooth,color=blue,mark=*,thick]
        {rnd};
        \legend{Something}
      \end{axis}
    \end{tikzpicture}
    \caption{Something}
    \label{figure_2_s}

    \begin{tikzpicture}[scale=0.9]
      \begin{axis}[
          width=\linewidth, % Scale the plot to \linewidth
          height=0.5\linewidth,
          grid style={dashed,gray!60},
          ylabel=Performance gain/drop percentage,
          yticklabel={\pgfmathprintnumber\tick\%},
          legend style={at={(1,0)},anchor=south east},
          xticklabels={,,},
          xlabel=Something
        ]
        \addplot[smooth,color=orange,mark=x,thick]
        {rnd};
        \addplot[smooth,color=blue,mark=*,thick]
        {rnd};
        \addplot[smooth,color=gray,mark=o,thick]
        {rnd};
        \legend{Something}
