TikZ 图片未在图形 fbox 中居中

我试图将 tikzpicture 正确置于子图/图形的中央，但它并没有正确居中。当我将 tikzpicture 放在 \fbox 中时，框架框正确居中，并且大小也根据 tikzpicture 而定，但 tikzpicture 不在框架框内。

下面是一些示例代码，用于存在相同问题的图形和子图形。在第二个代码中，我从 (0,0) 开始绘制第一条线，这似乎基本解决了居中问题（虽然我不知道为什么），但并不能完全解决垂直居中问题。到目前为止，我在这里找到的所有关于居中的类似问题都没有以这种方式表现。

答案1

\tikz{ .. }是 的简写形式\begin{tikzpicture} .. \end{tikzpicture}，您不想同时使用两者。删除\tikz{和结束的}。
