如何增加节点的背景颜色来输入文本

Question

显然我需要为右侧文本添加背景颜色。代码来自 Tantau 手册，第 45 页。这对我来说是个谜。保存文本的节点出了什么问题？如有任何答案，我将不胜感激。抱歉，我的英语水平很差。另外，我无法以简单的方式发布代码（每行手动添加 4 个空格？）如果能在此看到代码的结果，那就太好了。

Answer 1

问题来自options中定义的text height和。这样，它们适用于所有节点，而右侧文本是，因此其垂直大小由这些值定义。text depthtikzpicturenode

如果不使用text height和text depth，则所有其他节点都不会对齐，因此抑制它们并不方便。

由于我不知道如何将forget先前的值text height/depth应用于所有小节点都定义的特定节点，因此我能提供的最佳解决方案是将这些参数应用于其中scope。并在其外部声明正确的文本节点。
