Question

這裡有一種方法可以為您提供更好的起點。

主要步驟：

將重構套用至您的程式碼，請參閱例如此處了解更多信息
\tikzset已經figNode過時了（圖像消失了）
巨集並\newcommand簡化您的程式碼\graybox\colorcirc
類似的（新）樣式cmnnode和cmnbox
使您的“章節節點”能夠使用更大的字體進行多行顯示
重構仍然可以更進一步，例如吸收多個font語句（但這始終取決於程式設計師）

筆記：宏已經提供了;tikz 急需的分號。但如果您願意，您可以更改它，例如\graybox{(3.5,7)};（只需將其放在那裡）。

記住：內部的節點文字{ }接受任何 LaTeX“文字”，例如將某些單字加粗、在內部放置表格或圖像等。

您從這種方法中可以獲得什麼：

更乾淨的程式碼（美麗密碼），更多“口頭”地說明它將顯示的內容
「只改變一處」方法 ( styles, \newcommand)
更容易進一步調整以滿足您的需求

建議：如果您還沒有完成，請花一些時間閱讀本文開頭的教程PGF手冊，並尋找此處使用的 tikz 命令，例如透過 pdf 中的搜尋/尋找或索引。
