如何解决这个问题，只需要垂直转动箭头

    \end{tikzpicture}
    \caption{Test caption for vertical spacing}
\end{figure}

\end{document}

然后有第一个代码需要改变中间箭头的方向，但我尝试将代码跨度移动到下一个命令

`>>>>>>>>>>>>>>>>>>>>>>>---------------Here ------------------------------->>>>>>>`
              \node (bq) [anchor=north, yshift=13pt+\abovecaptionskip, rectangle, draw, fill=mgrau1] at (current page text area.north) {\small Posicionamiento de objetos por antena};
`>>>>>>>>>>>>>>>>>>>>>>--------------and There---------------------------->>>>>>>>`

但只能移动到中间上方，而不仅仅是在中间，箭头也可以扭转到北方向，但会有一个向上的位移，如上所述。
