如何在聊天栏中添加真实号码？

Question

我创建了以下条形图。

\begin{figure}[ht!]
  \caption{Accuracy comparison of A with other models}
  \scriptsize
\begin{tikzpicture}
\begin{axis}
  [symbolic y coords={A,B,C,D},
   ytick=data,
   xbar,
   y=0.5cm,
   enlarge y limits={abs=0.5cm},
   xlabel={Accuracy(\%)}
  ]
  \addplot[fill=blue] coordinates
    {(4.90,A)
     (5.05,B)
     (7.99,C)
     (24.67,D)          
    };
\end{axis}
\label{comparison}
\end{tikzpicture}
   \vspace{-1.5em}
\end{figure}

但我还必须在栏目顶部显示实际数字。我该怎么做？

但我需要得到类似下面的东西来显示实际数字。

\documentclass[tikz, border=1cm]{standalone} 
\usepackage{pgfplots}
\pgfplotsset{compat=1.18}
\begin{document}
\begin{tikzpicture}
\begin{axis}[
symbolic y coords={A,B,C,D},
ytick=data,
xbar,
xmin=0,
y=0.5cm,
enlarge y limits={abs=0.5cm},
enlarge x limits={abs=3,upper},
xlabel={Accuracy(\%)},
nodes near coords={\pgfmathprintnumber{\pgfplotspointmeta}\%},
nodes near coords style={orange},
]
\addplot[fill=blue] coordinates {(4,A) (5,B) (7,C) (24,D)};
\end{axis}
\end{tikzpicture}
\end{document}
