由于轴标签，Pgfplot 图形偏离中心

我的图形总是偏离中心，因为右轴比左轴更靠近图形。我每次都要手动将右轴延长一个特定的量吗？

在此处输入图片描述

\documentclass[tikz,border=3pt]{standalone}
\usepackage{pgfplots, pgfplotstable}
\usepackage{xcolor}
\usepackage{pgfplots}
\usepackage{tikz}




\begin{document}
\begin{tikzpicture}
    \begin{axis}[
        %width  = 0.85*\textwidth,
        %height = 8cm,
        %major x tick style = transparent,
        ybar,%=2*\pgflinewidth,
        bar width=20pt,
        %ymajorgrids = true,
        ylabel = {Deposition \%},
        symbolic x coords={{4  ac.h$^{-1}$},{6  ac.h$^{-1}$}},
        xtick = {{4  ac.h$^{-1}$},{6  ac.h$^{-1}$}},
        ymax=80,
        scaled y ticks = false,
        enlarge x limits=0.25,
        ymin=0,
        legend cell align=left,
        legend style={
                at={(1,1.05)},
                anchor=south east,
                column sep=1ex
        }
    ]


        \addplot [fill=black, draw=black,bar shift=3pt] coordinates {({4  ac.h$^{-1}$},61.66779959)}; %\addlegendentry{4  ac.h$^{-1}$}
\addplot [fill=white, draw=black,bar shift=-3pt] coordinates {({6  ac.h$^{-1}$},65.77432124)};
%\addplot [fill=white, draw=black, bar shift=0.5ex] table [x=X, y=6ACH]  {\datatable}; \addlegendentry{6  ac.h$^{-1}$}

这似乎不适用于独立文档类pgfplots 和图形居中

这是临时的：将 TikZ 图片置于某个区域的中心 Excel：5 秒，但没有 Tex 格式和错误字体。 在此处输入图片描述

答案1

如果您使用\begin{tikzpicture}[trim axis left, trim axis right]，轴将正确居中。

答案2

我想到的是简单地添加一个具有边界框大小的节点，其中inner xsep，同时使用轴作为边界框，overlay并且ylabel和yticklabel：

\usepackage{pgfplots}
\usetikzlibrary{fit}

\begin{tikzpicture}

    \begin{axis}[
        use as bounding box,
        ylabel style={overlay},
        yticklabel style={overlay},
        % ...
    ]
        % ...
    \end{axis}

    \node[
        draw=none,
        fit=(current bounding box.north west)
            (current bounding box.south east),
        inner xsep=5em % adjust as needed
    ] at (current bounding box.center) {};

\end{tikzpicture}

以此题为例，结果如下：

pgfplot 中心

当将其作为独立文件包含在另一个 TeX 文件中时，这也有效。
