Question

这里有一种方法可以为您提供更好的起点。

主要步骤：

将重构应用于您的代码，例如参见点击此处了解更多信息
\tikzset已figNode过时（图片已消失）
宏并\newcommand简化你的代码\graybox\colorcirc
cmnnode（新）风格也类似，cmnbox
使你的“章节节点”能够使用更大的字体进行多行显示
重构还可以更进一步，例如吸收多个font语句（但这始终取决于程序员）

笔记：宏已经提供了;tikz 急需的分号。但是，如果您愿意，您可以将其更改为\graybox{(3.5,7)};（只需将其放在那里）。

记住：节点内部的文本{ }接受任何 LaTeX“文本”，例如将某些单词加粗、在里面放置表格或图像等。

通过这种方法您可以获得以下好处：

更清洁的代码（美丽密码）更“口头”地说明它将展示什么
“仅在一个地方进行更改”方法（styles，\newcommand）
更容易进一步适应您的需求

建议：如果你还没有完成，请花一些时间阅读本章开头的教程。PGF 手册，并查找此处使用的 tikz 命令，例如通过该 pdf 内的搜索/查找或索引。
