如何水平移动条形图中的百分比数字？

Question

我想在水平方向上移动百分比数字，以使它们不重叠：

\documentclass{article}
\usepackage{pgfplots}
\pgfplotsset{compat=1.18}

\begin{document}
\pgfplotsset{testbar2/.style={
        xbar stacked,
        width=0.8\textwidth,
        xmajorgrids = true,
        xmin=0,xmax=100,
        ytick = data, yticklabels = {1,2},
        tick align = outside, xtick pos = left,
        bar width=6mm, y=13mm,
        nodes near coords={\pgfmathprintnumber{\pgfplotspointmeta}\%}, % <-- prints % sign after y coordinate value
        xticklabel={\pgfmathprintnumber{\tick}\%},% <-- prints % sign after x tick value
        nodes near coords align={center}, % <-- horizontal alignment centered of nodes 
        enlarge y limits=0.75, % <-- Adds vertical space so to not crop the bars
}}
\begin{figure}
    \centering
    \begin{tikzpicture}
        \begin{axis}[testbar2, legend style={at={(0.5,-0.3)}, anchor=north,legend columns=-1},
            /tikz/every even column/.append style={column sep=0.2cm}, every node near coord/.append style={yshift=0.5cm},
            ]
            \addplot coordinates{(20.00,1) (22.60,2)};
            \addplot coordinates{(28.57,1) (23.10,2)};
            \addplot coordinates{(11.43,1) (12.14,2)};
            \addplot coordinates{(28.57,1) (23.70,2)};
            \addplot coordinates{(6.43,1) (8.07,2)};
            \addplot coordinates{(5.00,1) (10.39,2)};
            \legend{A,B,A\textsubscript{1},B\textsubscript{1},A\textsubscript{2},C}
        \end{axis}
    \end{tikzpicture}
\end{figure}
\end{document}

这可以是一种替代方案。

\documentclass{article}
\usepackage{pgfplots}
\pgfplotsset{compat=1.18}

\pgfplotsset{,
    xmin=0,
    /tikz/font=\footnotesize,
}
\begin{document}
    \begin{figure}
    \centering
    \begin{tikzpicture}
    \begin{axis}[
        height=85pt,
        width=\axisdefaultwidth,
        xmajorgrids = true,
        xmin=0,xmax=100,
        ytick = data, yticklabels = {1,2},
        xtick={0,20,...,100},
        tick align = outside, xtick pos = left,
        x post scale=1.3,   
        scale only axis,
        enlarge y limits=0.75, 
        xbar stacked,
        bar width=6mm, y=14mm,
        ytick=data,
        nodes near coords={\pgfmathprintnumber{\pgfplotspointmeta}\%},
        nodes near coords style={yshift=(-1)^\plotnum * 13pt},% shifts up or down nodes near coords <<<
        xticklabel={\pgfmathprintnumber{\tick}\%},% <-- prints % sign after x tick value
        legend style={at={(0.5,-0.3)}, anchor=north,legend columns=-1},
        ]
        \addplot coordinates{(20.00,1) (22.60,2)};
            \addplot coordinates{(28.57,1) (23.10,2)};
            \addplot coordinates{(11.43,1) (12.14,2)};
            \addplot coordinates{(28.57,1) (23.70,2)};
            \addplot coordinates{(6.43,1) (8.07,2)};
            \addplot coordinates{(5.00,1) (10.39,2)};
            \legend{A,B,A\textsubscript{1},B\textsubscript{1},A\textsubscript{2},C}         
        \end{axis}
    \end{tikzpicture}
    \end{figure}
\end{document}

yshift 取自将坐标附近的节点向上或向下移动

我会旋转图片并在条形侧面写上标签：

%\documentclass{article}
\documentclass[margin=3mm]{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=1.18}

\begin{document}
    \begin{tikzpicture}
\begin{axis}[width=66mm,
    ybar stacked,
    ymajorgrids = true,
    xtick = {1,2},
    xmin=0.5, xmax=3,
    ymin=0, ymax=100,
    yticklabel={\pgfmathprintnumber{\tick}\%},
%
    nodes near coords={\pgfmathprintnumber{\pgfplotspointmeta}\%},
    nodes near coords style={font=\scriptsize, anchor=west, xshift=1ex},
%
legend style = {at={(0.5,-0.12)},
                anchor=north, font=\small,
                legend columns=-1},
    ]
\addplot coordinates{(1, 20.00) (2, 22.60)};
\addplot coordinates{(1, 28.57) (2, 23.10)};
\addplot coordinates{(1, 11.43) (2, 12.14)};
\addplot coordinates{(1, 28.57) (2, 23.70)};
\addplot coordinates{(1,  6.43) (2,  8.07)};
\addplot coordinates{(1,  5.00) (2, 10.39)};

\legend{A,B,
        A\textsubscript{1},B\textsubscript{1},
        A\textsubscript{2},C}
\end{axis}
\end{tikzpicture}

\end{document}
