更大的 gnuplot 生成的 TikZ TeX 无法编译

Question

（以防其他人想知道如何实现这一点。）

采用更简单的 Gnuplot 脚本，例如：

set terminal tikz size 5,4 createstyle
set output "demo.tex"
plot sin(x)

与您的脚本相比，添加了一个关键内容：

createstyle

该选项意味着会创建一些额外的文件，如下面的终端输出所示。这些文件包含 TikZ 代码中使用的样式定义。

plots$ ls
tikzout.gnu
plots$ gnuplot tikzout.gnu 
plots$ ls
demo.tex                     gnuplot-lua-tikz.sty  t-gnuplot-lua-tikz.tex
gnuplot-lua-tikz-common.tex  gnuplot-lua-tikz.tex  tikzout.gnu

各种文件包含 LaTeX ( gnuplot-lua-tikz.sty)、ConTeXt ( t-gnuplot-lua-tikz.tex) 和纯 TeX ( gnuplot-lua-tikz.tex) 的代码。

然后，使用 Gnuplot 输出的最小 LaTeX 文档将是

\documentclass[border=5mm]{standalone}
\usepackage{gnuplot-lua-tikz}
\begin{document}
\input{demo}
\end{document}

生成的文件gnuplot-lua-tikz会加载 TikZ 包（因此\usepackage{tikz}不是必需的），并定义所有必要的样式。输出如下：

（虽然情节不太好看，但无论如何这只是一次示范。）

作为参考，demo.texGnuplot 生成的文件如下所示。
