以符号 y 坐标更改 y 范围

Question

我有以下 tikz 代码

\begin{tikzpicture}
\begin{axis}[
                    xbar,
                    y axis line style = {opacity = 0},
                    axis x line       = none,
                    tickwidth         = 0pt,
                    enlarge y limits  = 1.8,
                    legend style={at={(0.91,0.8)},anchor=east},
                    symbolic y coords = {2016,2009},
                    ytick             = data,
                    nodes near coords
                  ]

\addplot [color=black,fill=red]  coordinates { (8518,2009)     (10891,2016) };
\addplot [color=black,fill=blue] coordinates { (5827,2009)     (5845,2016)  }; 

\legend{DEB,LMR}
\end{axis}
\end{tikzpicture}

这给了我这个：

tiikz 图通过以下方式包含到我的主要 .tex 文件中

 \begin{figure}[!htb]                                                                             
    \centering                                                                                   
    \input{barchart.tex}                         
    \caption{Here is the description of the plot}                                   
    \label{fig:barchartplot}
 \end{figure}

但是，条形图的上方和下方都留有大量空白。我该如何“剪切”此图像？上方和下方都有很多文本，我不希望图像周围有那么多“白色区域”！

提前感谢您的帮助！

Answer 1

默认值为bar width10pt，y 值相同的两个条形之间的间隔为 2pt（默认值）。您有两个图，因此和xbar=2pt之间所需的空间至少为 (2*10pt+2pt)+2pt=24pt。因此您可以使用20092016

y=30pt,
enlarge y limits={abs=15pt}% the value must be at least half of y

然后你必须删除enlarge y limits = 1.8并更改legend style。一种可能性是

legend style={at={(1,1-|{axis cs:10891,2016})},anchor=north east},

其他

legend style={at={(1,1-|{axis cs:10891,2016})},anchor=south east},

还有其他可能性。

代码：

\documentclass{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=1.13}
\begin{document}
\begin{tikzpicture}
\begin{axis}[
                    y=30pt,
                    enlarge y limits={abs=15pt},
                    xbar,
                    y axis line style = {opacity = 0},
                    axis x line       = none,
                    tickwidth         = 0pt,
                    %legend style={at={(1,1-|{axis cs:10891,2016})},anchor=north east},
                    legend style={at={(1,1-|{axis cs:10891,2016})},anchor=south east},
                    symbolic y coords = {2016,2009},
                    ytick             = data,
                    nodes near coords
                  ]

\addplot [color=black,fill=red]  coordinates { (8518,2009)     (10891,2016) };
\addplot [color=black,fill=blue] coordinates { (5827,2009)     (5845,2016)  }; 

\legend{DEB,LMR}
\end{axis}
\end{tikzpicture}
\end{document}
