Pgfplots/Tikz 图形未居中

Question

我有下面的图表但我不知道为什么它没有居中。

以下是作为最小工作示例的代码：

\documentclass[]{thesis}

\usepackage{graphicx}
\graphicspath{{figures/}} % folder


\usepackage{pgfplots}
\pgfplotsset{compat=1.10}
\usepgfplotslibrary{dateplot}
\usepgfplotslibrary{fillbetween}
\usetikzlibrary{patterns}

\begin{document}

\begin{figure}[h]
    \centering
    \begin{tikzpicture}
    \begin{axis}[
    xbar, 
    y = 1.2cm,
    y axis line style = { opacity = 0 }, 
    hide x axis, 
    tickwidth = 0pt,
    xmin=0, 
    xlabel={Percentage \%},
    enlarge y limits  = 0.2,
    enlarge x limits  = 0.02,
    bar width=15pt,
    symbolic y coords={%
        {Drunken driving},
        {Unadjusted speed},
        {Insufficient safety distance},
        {Not respecting right of way},
        {Turning, U-turn, reversing, entering the flow of traffic, starting off the edge of the road}},
    nodes near coords={\pgfmathprintnumber\pgfplotspointmeta\%},
    nodes near coords align={horizontal},
    ytick=data,yticklabel style={text width=10cm,align=right,font=\linespread{1.2}\selectfont},
    ]
    \addplot[style={blue,fill=blue,mark=none}] coordinates {
        (3,{Drunken driving})
        (10.7,{Unadjusted speed})
        (15.9,{Insufficient safety distance}) 
        (17.3,{Not respecting right of way}) 
        (19,{Turning, U-turn, reversing, entering the flow of traffic, starting off the edge of the road})
    };
    \end{axis}
    \end{tikzpicture}
    \caption{Causes of accidents with personal injuries caused by human error in Germany in 2018.}
    \label{fig:accidents}
\end{figure}

\end{document}

Answer 1

text width正如我最初怀疑的那样，这是由 的设置导致的yticklabel style，这会使这些节点非常宽。避免猜测适当宽度的一种方法是添加scale only axis,width=0.45\textwidth到选项中，然后在 中axis使用。text width=0.45\textwidthyticklabel style

至于小的错位，这是由于文本高度和文本深度造成的。一个快速的解决方法是添加\strut到font的键yticklabel style。
