我pgfplots在 中有一个图形pgfplotstable，并且图形的一部分与表格重叠，就像您在该图中所看到的一样：
顶部的 800 被表格边框切掉。
以下是 MWE：

是否可以使表格边框背景透明以便正确显示 800？
我知道我的 MWE 并不是真正最小的。我发了这么多帖子，因为我会确保如果在这个例子中解决了问题，问题就会得到解决，而且我知道我管理代码的方式不是最佳方式，所以这方面也允许提出建议。即使这不是最佳方式，它也可能激发其他对类似结果感兴趣的人。我知道问题背后的物理学没有得到尊重，这是一个从绘图角度的例子
答案1
单独运行 tikzpicture 会导致被800剪切。通过扩展 y 限制 enlarge y limits = {abs=0.7},可以解决此问题。
此外，您还可以使用\raisebox来调整对齐方式。请注意， 的第一个参数\raisebox会移动基线，这不会产生任何效果。第二个参数会更改（表观）高度。 是3.05cm通过反复试验获得的。
