![背景文字如何定位?](https://linux22.com/image/415772/%E8%83%8C%E6%99%AF%E6%96%87%E5%AD%97%E5%A6%82%E4%BD%95%E5%AE%9A%E4%BD%8D%EF%BC%9F.png)
我有两个问题。如何放大背景并更改文本的位置?以及,为什么最后一个梯形比其他图形大?
这是我的 WE:

答案1
请注意,\tikzstyle
现在已弃用。\tikzset
建议改用。您的代码只需稍作更改即可满足您的要求:
- 将
MAPDL
节点放在(static) -- (seval)
前层的路径上 - 然后让适合的背景节点
(static)(seval)(mapdl)
只负责着色 - 使用
trapezium stretches body
适合您data
风格的选项
