所以我想把我的tikzpicture放在一个盒子里，但每当我使用\draw (a) to[out=0, in=180] (b)它时，图片都会从最初的 14x8 图片扩展到更宽的图片，并且居中看起来很奇怪。我尝试了除 之外的其他方法\draw (a) to[out=0, in=180] (b)，但看起来不太好。
这是我的代码：
\begin{figure}[H]

弯曲的绿线看起来就像我想要的那样，但它们似乎将图片延伸到了我绘制的框之外，现在它不再居中了。第一张图显示了我希望用曲线呈现的图片外观，第二张图显示了我希望居中的外观。
答案1
好吧没关系，我找到了解决方案：
只需将边框插入为\useasboundingbox (0,0) rectangle (14,8);，它就会删除边框外的所有内容，这意味着居中将再次按预期工作。
