Tikz 中节点文本的垂直对齐

Tikz 中节点文本的垂直对齐

有人能告诉我为什么文本是顶部对齐的，例如我字母将文本向下移动，但o仍然粘在顶部，从而导致两个节点错位？

我希望文本垂直居中，两个字母，我和o处于同一高度。

代码由@JasperHabicht 提供： https://tex.stackexchange.com/a/711612/262813

我尝试调整设置并得出以下结论：

[baseline=(a), >=stealth,每个节点/.style={最小高度=10ex,文本深度=10ex,align=center}]`

但没有成功。

经过@cfr的修正，（A）周围的可选形状被锚定在低位：

\begin{document}
    
    
    \coolsource[source,v][draw]{ion,n;ory,n;i,n;i,n}

解决办法就是anchor=south保持节点（A）的设置。

我无法按原样编译您的示例，因此我删除了自定义字体设置。要将节点与基线对齐，请使用base、base west等base east。我猜这就是您想要的，但是，如果您确实希望它居中，请使用center、west和east。

我不清楚expl3在这里使用 对你有多大帮助。请注意，此语法不一定与 pgf/tikz 语法兼容，因此你完全有可能遇到冲突。话虽如此，我也将它们混合使用 - 只是你需要对潜在的陷阱稍微警惕一点。
