This snippet is unbalanced.

There is no closing '}' for
    \subfloat[Subcaption for First Part]{

You should be getting messages in the .log  file indicating
a problem somewhere.
This *must* have some effect upon your output.
Just what, might depend upon which document-class
you are using, and whatever other packages are loaded.


When the \subfloat is closed between the  \] and  \caption ,
then the \ref works properly, in my testing.
However the use of \[ ... \]  produces a warning.
Why do you need displayed-math here?
The Xy-pic diagram works fine inline as well.

Alternatively, put in an extra \vbox :

\begin{figure}[tbp]
\centering
\subfloat[Subcaption for First Part]{\label{subfig:continued:first} % 
% label for first subfigure
\vbox{Some text here:\par   %% <---- \vbox  and \par
1.\quad
\[ \mbox{ \xygraph{   %% <----  the \mbox is redundant here !!
!{<0cm,0cm>;<1cm,0cm>:<0cm,1cm>::}
!{(0,0) }*+{\bullet_{a}}
!{(1,1) }*+{\bullet_{b}}
!{(2,0) }*+{\bullet_{c}}
!{(3,-1)}*+{\bullet_{d}}
} } \]
}}   %% <-----------  end of \vbox  and of  \subfloat
\caption{Example of Continued Figure (Empty graph)}
\label{fig:continued:first} %% label for first figure
\end{figure}

Hope this helps,
