pgfplots raw gnuplot 由于 babel ngerman 无法正常工作

Question

考虑以下 MWE

% !TeX program = lualatex
\RequirePackage{luatex85}
\documentclass[border=1pt]{standalone}

\usepackage{pgfplots}
    \pgfplotsset{compat=newest}

\usepackage[main=ngerman,english]{babel}

\begin{document}

\centering
\begin{tikzpicture}
    \begin{axis}[
        width=10cm, height=7cm,
        tick label style={font=\large},
        xmin=4675.5, xmax=4676.5,
        xtick={4675.5,4675.8,...,4676.5},
        axis x line=box,
        axis y line=box,
        xlabel=$x$-values,
        ylabel=$y$-values,
        xlabel shift=0pt,
        ylabel shift=0pt
    ]
    \addplot gnuplot [raw gnuplot, id=test, mark=none]{
    set xrange [4675.5:4676.5];
    set yrange [0.05:0.065];
    plot "samples.dat" using ($1):($2) with lines;
    };

    \end{axis}
\end{tikzpicture}

\end{document}

使用二维样本数据（取自另一篇 SO 文章）

为什么加载时没有显示任何图表babel？预期结果：

Answer 1

问题在于babel改变了双引号的含义"。

添加\shorthandoff{"}before\addplot即可解决问题。请注意，变音符号 shothand 处理将被禁用，直到下一个\end{...}。

Answer 2

如果我添加，就没有问题了\usetikzlibrary{babel}。

\RequirePackage{luatex85}
