我怎样才能在带有水平堆叠条的 tikzpicture 侧面添加箭头？

Question

绘制的图像就是我想要的。我已经有了水平条，我只需要 y 轴标签。此外，我如何将百分比添加到 x 轴值和条形图内的值中？这是我目前所拥有的：

\begin{tikzpicture}
        %\draw (0,0) rectangle (6,6); %create a bounding box to reserve space
        %\begin{pgflowlevelscope}{\pgftransformscale{.79}}
        \begin{axis}[
        name=MyAxis,
        xbar stacked,
        width=10cm, height=10.0cm, 
        bar width=8pt,
        nodes near coords,
        nodes near coords style={
            font=\scriptsize,
        },
        xmin=0, xmax=100,
        %enlargelimits=0.15,
        %enlarge y limits=0.5,
        %enlargelimits=0.07,
        legend style={at={(0.5,1)}, anchor=south, legend columns=-1, draw=none},
        tick label style={font=\small}, 
        %tickwidth = 0pt, 
        ylabel={Label 1},
        symbolic y coords={P11, P12, P61, P62, P81, P82},
        ytick=data,
        ]
        \addplot coordinates {(70,P11) (50,P12) (74,P61) (65,P62) (55,P81) (43,P82)};
        \addplot coordinates {(70,P11) (50,P12) (74,P61) (65,P62) (55,P81) (43,P82)};
        \addplot coordinates {(70,P11) (25,P12) (74,P61) (65,P62) (55,P81) (43,P82)};
        \addplot coordinates {(70,P11) (25,P12) (74,P61) (65,P62) (55,P81) (43,P82)};
        \addplot[color=violet, fill=violet!50] coordinates {(4,P11) (8,P12) (1,P61) (2,P62) (5,P81) (19,P82)};
        \legend{\strut A, \strut D, \strut L, \strut P, \strut T}
        \end{axis}
\end{tikzpicture}%

请注意，由于您的设置，图表中的大部分条形图被剪掉了，但我认为这是故意的。一般来说，你可以使用yticklabel cs旁边绘制一些东西是勾选标签，例如使用\draw[<->] (yticklabel cs:0) -- (yticklabel cs:0.5) node[midway, left] {Label 1};。但是，由于您似乎需要剪切图，因此您无法直接在环境内执行此操作，axis因为它会与图一起被剪切掉。一种解决方法是将 放置\coordinate在axis环境内，并使用这些在环境外的标签处绘制事物。

因此，你可以做这样的事情：

\documentclass[border=10pt]{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=newest}

\begin{document}
\begin{tikzpicture}
    \begin{axis}[
        name=MyAxis,
        xbar stacked,
        width=10cm, height=10cm, 
        bar width=8pt,
        nodes near coords,
        nodes near coords style={
            font=\scriptsize,
        },
        xmin=0, xmax=100,
        %enlargelimits=0.15,
        %enlarge y limits=0.5,
        %enlargelimits=0.07,
        legend style={at={(0.5,1)}, anchor=south, legend columns=-1, draw=none},
        tick label style={font=\small}, 
        %tickwidth = 0pt, 
        %ylabel={},
        symbolic y coords={P11, P12, P61, P62, P81, P82},
        ytick=data,
    ]
        \addplot coordinates {(70,P11) (50,P12) (74,P61) (65,P62) (55,P81) (43,P82)};
        \addplot coordinates {(70,P11) (50,P12) (74,P61) (65,P62) (55,P81) (43,P82)};
        \addplot coordinates {(70,P11) (25,P12) (74,P61) (65,P62) (55,P81) (43,P82)};
        \addplot coordinates {(70,P11) (25,P12) (74,P61) (65,P62) (55,P81) (43,P82)};
        \addplot[color=violet, fill=violet!50] coordinates {(4,P11) (8,P12) (1,P61) (2,P62) (5,P81) (19,P82)};
        \legend{\strut A, \strut D, \strut L, \strut P, \strut T}

        \coordinate (A) at (yticklabel cs:0);
        \coordinate (B) at (yticklabel cs:0.5);
        \coordinate (C) at (yticklabel cs:1);
    \end{axis}
    \draw[<->, shorten >=5pt, shorten <=5pt] (A) -- (B) node[midway, left] {Label 1}; 
    \draw[<->, shorten >=5pt, shorten <=5pt] (B) -- (C) node[midway, left] {Label 2}; 
\end{tikzpicture}%
\end{document}
