第一次在这个论坛上发帖。我使用了一个模板来制作这个功能分析树。（还没有完全完成，因为我想先把格式弄对）。但是当我编译它时，图形被强制放在页面顶部，而不是在页面中心居中。我不确定如何做到这一点，因为我已经尝试了很多可能性，浏览了这个论坛。
非常感谢您提供的任何帮助！

尝试将您的tikzpicture内部figure环境而不是center环境放置其中。
\begin{figure}[p]
\centering
\begin{tikzpicture}
....
\end{tikzpicture}
\caption{if required \label{if required too}}
\end{figure}
该[p]选项将图形放在单独的页面上
