问题：无法在 LyX 中显示 TikZ 代码下方的文本”

我目前在 LyX 中面临一个挑战，在输入几行文本后，我将 TikZ 代码插入 TeX 框内或直接插入到 apex 序言中。但是，我发现 TikZ 代码后面的文本不可见。如果将代码放在序言中，我在文档中编写的文本均不可见。我正在寻求帮助来解决这个问题，并了解如何确保在 LyX 中正确显示插入的 TikZ 代码下方的文本。任何指导或解决方案都将不胜感激。

不作为解决方案，仅作为参考。

在其中一个 LyX 视图中查看完整的源文档应该与此类似：

  • 序言中有很多不同之处，但至少与下面提到的软件包不同
  • 文件主体原样

顺便说一句，我没有花精力重构你的Tikz代码，只是想提供参考。

% ~~~ this is a regular preamble in LaTeX ~~~~~~~~~~~~~~~~~~
\documentclass[10pt,a4paper]{article}
\usepackage{tikz}
\usetikzlibrary{arrows.meta,positioning}% <<<
\usepackage{blindtext}  % provides some dummy text

% ~~~ next, this is the document ~~~~~~~~~~~~~~~
\begin{document}

 % ~~~ text before the tikypicture ~
 \blindtext[1]

 \begin{tikzpicture}[->,
    >={Stealth}, % <<<
    auto,node distance=2.5cm,
     thick,
     main node/.style={circle,draw,font=\sffamily\Large\bfseries, minimum size=1cm},
     align=center]

    \node[main node] (s) {$s$};
    \node[main node] (v1) [below right=0.8cm and 1.8cm of s] {$v_1$};
    \node[main node] (v2) [above right=0.8cm and 1.8cm of s] {$v_2$};
    \node[main node] (vn-3) [right=1.2cm of v1] {$v_{n-3}$};
    \node[main node] (vn-2) [right=1.2cm of v2] {$v_{n-2}$};
    \node[main node] (t) [below right=0.8cm and 1.8cm of vn-2] {$t$};
    
    \draw [->] (s) -- (v1);
    \draw [->] (s) -- (v2);
    \draw [->] (vn-3) -- (t);
    \draw [->] (vn-2) -- (t);
    
    \draw [dashed] [->,blue] (v1) -- (vn-2);
    \draw [dashed] [->,blue] (v2) -- (vn-3);

好的，之后关于 Latex 代码的参考，这里有一个解决方案，假设您在使用 LyX 时可能遇到了麻烦。

可能有效的程序是这样的，其中我强调了menu- and dialogbox actions：

  • 从模板创建一个新的 Lyx 文件
  • 如果需要，可以通过以下方式更改 DocumentclassDocument/Settings
  • 输入文本，正如你所做的那样
  • insert TEX，然后进入例如 tikzpicture 环境
  • 通过Document/Settings, LaTeX preamble输入 LyX 中其他地方未列出的包以避免编译错误（缺少包）Apply，，Close
  • 之后继续写
  • export需要时转换为 .pdf

此屏幕截图比较了 LyX 主窗口、LaTeX 预览和所描述的各种菜单操作的结果：

微软视窗系统

这是导出的 .pdf 的屏幕截图：

pdf

请注意，LaTeX 预览大致如下我的参考：

  • LyX 更改了序言，但您也可以在此处查看相关部分
  • 之后的内容部分\begin{document}几乎与描述的一样，只是偶尔有一点 LyX 的干预

顺便说一下，这是上面截图中的 Lyx 文件：

 Next insert TEX and type:

This won't compile as the tikz-package is missing.
 So:
