我从上个月开始就一直这样做。我想使用
\documentclass[a4paper,11pt]{report}
但是如果我使用上述配置（我想要使用）流程图不会显示在一页中，我该如何解决这个问题？请帮我完成流程图。
1) 我该如何为此写标题？
2）还有其他简单的乳胶包可以做到这一点吗？

您可以使用adjustbox包及其adjustbox环境并获取标题，使用figure环境：
\begin{figure}[htbp]
\begin{adjustbox}{max height=0.9\textheight,center} %% adjust max height
your tikz code
\end{adjustbox}
\caption{This is my flow chart}
\end{figure}
