pgfplots - 如何将背景填充到“坐标附近的节点”？

我希望每个图的节点/值都用 填充white，这样网格就会被透支。这可能吗？

网格上有数字/节点的图片

来自pgfplots手册：

/pgfplots/every node near coord (style, no value) 用于由坐标附近的节点生成的每个节点的样式。它最初是空的。

因此（Ctrl-F NEW在代码块中找到相关行）：

\documentclass[

  Fx,-70.35,0.5,0.6,60,1,0.5
  Fy,-40,0.5,0.6,50,1.91,1.5
  Fz,-20,0.42,0.6,40,4,0.5
\end{filecontents}

\pgfplotstableread[col sep=comma]{force-stats.txt}{\tableabcdef}

\begin{document}
\begin{center}
  \begin{tikzpicture}[font=\small]
    \begin{axis}[
      scale only axis=true,

      %
      symbolic x coords={Fx,Fy,Fz},
      %
      xtick=data,
      nodes near coords,
      every node near coord/.style={fill=white},%NEW
      xticklabels={{\(F_{x}\)},{\(F_{y}\)},{\(F_{z}\)}},
      ]
      \addplot+[nodes near coords align={above}] plot [error bars/.cd, y dir=both, y explicit] table [col sep=comma, x=Stats, y=Max, y error=MinCIP95] {\tableabcdef};
      \addplot+[nodes near coords align={below}] plot [error bars/.cd, y dir=both, y explicit] table [col sep=comma, x=Stats, y=Min, y error=MinCIP95] {\tableabcdef};
    \end{axis}
  \end{tikzpicture}
\end{center}
\end{document}

将该选项添加到周围tikzpicture没有任何效果（我猜在这种情况下网格是稍后绘制的），但正如您所看到的，将其添加到作品中axis。

但结果并不一定令人满意：
