I would like to generate a .pdf standalone figure of the following tikzpicture. I have tried the common examples of standalone tikzpictures but it does not work.

\documentclass{article}

% next line is to put the framebox

    \label{fig:label}
\end{figure}

\end{document}

which produce this:

enter image description here

I think it is because of the definition uses drawgrid command and I do not know how to adapt it to a standalone picture.

All you need to change is to delete several lines that are meaningless in standalone-class. Delete the figure environment, the \caption- and \label-part. Also, the \centering is not necessary.
