向带有标签和类别的散点图添加误差线

我想要做的是在每个点上添加一个垂直误差线（表格中的列）。我尝试添加：

%error bars/.cd,
%y dir=both,
%y explicit,

但它没有起作用。

\documentclass[a4paper,10pt]{scrartcl} 
\usepackage{pgfplots}
\begin{document}

\begin{figure}[t]
    \centering
    \begin{tikzpicture}[scale=0.7]
    \begin{axis}[
    %axis x line=center,
    xtick pos=left,
    ytick pos=left,
    axis y line*=left,
    axis x line*=left,
    ylabel near ticks,
    xlabel near ticks,
    xlabel=Requirement (\#sentences),
    ylabel=mean F1,
    %axis y line=none,
    %hide y axis,
    xmin=-50,xmax=320,
    ymin=40, ymax=100,
    xtick={0, 100, 200, 300},
    xticklabels={0, 100, 100 + 100, highres},
    %xticklabel style={rotate=20},
    ]

    \addplot[
    scatter/classes={a={blue}, b={red}, c={green}, d={black}},
    scatter,
    only marks,%
    %error bars/.cd,
    %y dir=both,
    %y explicit,
    scatter src=explicit symbolic,
    nodes near coords*={\Label},
    visualization depends on={value \thisrow{label} \as \Label},
    ]%
    table[meta=class, x=x, y=y, y error=ey]{
        x   y   ey  class   label
        0   72  3   a   model1
        100 77  2   b   model2
        200 63  5   c   model3
        300 89  7   d   model4
    };
    \end{axis}
    \end{tikzpicture}
    \caption{}
\end{figure}
\end{document}

现在我添加了声明图 [误差线/.cd，y dir = both，y 显式]并且误差线在那里，但是它们在标签中，我需要移动标签以便它们清晰，有什么想法吗？

\begin{figure}[t]
    \centering
    \begin{tikzpicture}[scale=0.7]
    \begin{axis}[
    %axis x line=center,
    xtick pos=left,
    ytick pos=left,
    axis y line*=left,
    axis x line*=left,
    ylabel near ticks,
    xlabel near ticks,
    xlabel=Requirement (\#sentences),
    ylabel=mean F1,
    %axis y line=none,
    %hide y axis,
    xmin=-50,xmax=320,
    ymin=40, ymax=100,
    xtick={0, 100, 200, 300},
    xticklabels={0, 100, 100 + 100, highres},
    %xticklabel style={rotate=20},
    ]

    \addplot[
    scatter/classes={a={blue}, b={red}, c={green}, d={black}},
    scatter,
    only marks,%
    %error bars/.cd,
    %y dir=both,
    %y explicit,
    scatter src=explicit symbolic,
    nodes near coords*={\Label},
    visualization depends on={value \thisrow{label} \as \Label},
    ]%
    plot [error bars/.cd, y dir = both, y explicit]
    table[meta=class, x=x, y=y, y error=ey]{
        x   y   ey  class   label
        0   72  3   a   model1
        100 77  2   b   model2
        200 63  5   c   model3
        300 89  7   d   model4
    };
    \end{axis}
    \end{tikzpicture}

比实际答案更有用的可能是如何搜索并找到此类帖子。我所做的就是在 Google 上搜索图片site:tex.stackexchange.com error bars nodes near coords，点击有希望的图片，然后尝试选择一张看起来相当优雅的图片。
