我试图包含用 gnuplot 创建的图像。因此我在 gnuplot 中使用：
set terminal epslatex color
set output './bild.tex'
现在尝试将图像包含在我的 tex 文档中：
\begin{figure}
\input{bild.tex}
\end{figure}
给出了错误：
“额外}，或者被遗忘的 \endgroup。\end{figure}”
我根本不知道自己做错了什么。
编辑：例如：
\documentclass[11pt,titlepage]{scrartcl}
\usepackage[british,UKenglish,USenglish,english,american]{babel}
\usepackage[utf8]{inputenc}
\begin{document}
\begin{figure}
\input{bild.tex}
\end{figure}
\end{document}
我在这里先向您的帮助表示感谢！

以下是bild.tex的代码：

答案1
正如您所尝试的，您显示的文件.tex似乎是用于包含在内\input。
当您尝试这样做时，您会在控制台和日志中得到输出。这会告诉您一些有用的东西，例如，您需要在序言中加载诸如 之类的内容color.sty。（但最好改为加载\usepackage{xcolor}。）
我收到的第一个错误是
! Package graphicx or graphics not loaded.
因此，添加
\usepackage{graphicx}
如果收到缺失错误color.sty，还请添加
\usepackage{xcolor}
我不明白，但我没有./bild，所以这并不奇怪。如果此文件是 EPS，则将.eps扩展名添加到文件将能够graphicx找到它并进行转换。如果不是，添加此扩展名显然会使事情更加混乱。
\documentclass[11pt,titlepage]{scrartcl}
\usepackage[british,american]{babel}% US is default; UK is a second available language
\usepackage[utf8]{inputenc}
\usepackage[demo]{graphicx}% remove demo - you have bild, but I don't!
\begin{document}
\begin{figure}
\input{bild}
\end{figure}
\end{document}
因为我必须使用demo模式，所以效果并不十分令人印象深刻：
