我正在生成此图像并遇到了这个 LaTeX 代码，但是当我运行它时它会使图像变平。

只是为了好玩：有些人试图添加一些有点让人联想到的功能positioning-plus。这无法与图书馆竞争，但足以或多或少地重现图表，

答案2
渴望评论：
测试您的 MWE 我得到了正确的节点位置，但是文本不可见。我需要\text=black向所有节点添加样式定义。这样做，我稍微缩短了样式名称并重新组织了箭头的绘制：
\documentclass[tikz,border=10pt]{standalone}

HN/.style = {draw, fill=white,
Minimum Width=header nodes,
font=\Large\ttfamily, text=black,
text depth=0.5ex, text height = 2ex},
header/.style = {%inner ysep = +1.5em,
append after command = {\pgfextra{\let\LN\tikzlastnode}
node [HN] (header-\LN) at (\LN.north) {#1}
node (h-\LN) [span=(\LN)(header-\LN)] at (fit bounding box){}
}
},
hv/.style = {to path = {-|(\tikztotarget)\tikztonodes}},
vh/.style = {to path = {|-(\tikztotarget)\tikztonodes}},
fat blue line/.style = {ultra thick, blue}
}
\begin{document}

为了获得上述结果，您需要至少编译 MWE 两次。
