# How to position XY-pic package drawings

I have this basic XY-pic package draw

\begin{displaymath}
\xymatrix{A & B \\
C & D }
\end{displaymath}


And when i enter the code in Latex, it draws it in the center of the page. How can i position this draw exactly the way i want it?

P.S. Also, how do you throw any drawing into a box in latex?

Try

 \documentclass{amsart}
\usepackage{tikz}
\usepackage{graphicx}
\usetikzlibrary{calc}
\usepackage[all]{xy}
\begin{document}
\hfill{}This matrix \fbox{\xymatrix{A & B \\ C & D }} is off to the right.
\begin{center}
This matrix \fbox{\xymatrix{A & B \\ C & D }} is centered.
\end{center}
\par\noindent{}This one \fbox{\xymatrix{A & B \\ C & D }} is on the left.
\begin{tikzpicture}[remember picture,overlay]
\node[anchor=south west,inner sep=0pt] at ($(current page.south west)+(0cm,0cm)$) {
\fbox{\xymatrix{A & B \\ C & D }}
};
\node[anchor=south east,inner sep=0pt] at ($(current page.south east)+(0cm,0cm)$) {
\fbox{\xymatrix{A & B \\ C & D }}
};
\node[anchor=north west,inner sep=0pt] at ($(current page.north west)+(0cm,0cm)$) {
\fbox{\xymatrix{A & B \\ C & D }}
};
\node[anchor=north east,inner sep=0pt] at ($(current page.north east)+(0cm,0cm)$) {
\fbox{\xymatrix{A & B \\ C & D }}
};
\end{tikzpicture}
\end{document}


This results in output like:

• Hey Ben, what are you doing here? What are trying to accomplish with that first piece of code? I'm asking if i can place this xy-pic in whatever position i want. – Josh Jul 4 '17 at 13:55
• When you say "whatever position", do you mean left, right, center, or do you mean at whatever coordinate location on the page? How do you want to specify the position? – Benjamin McKay Jul 4 '17 at 14:17
• I mean literally whatever position and i'm the one asking if i'm able to do that in teh first place. Or atleast how do i specify it to be in the left for example. – Josh Jul 4 '17 at 18:23
• I show above how to get a box around the matrix, and how to get the matrix to the left side of the text area. I will have to look up how to get a precise (x,y) coordinate location on the page. – Benjamin McKay Jul 4 '17 at 18:34
• I appreciate your help. – Josh Jul 4 '17 at 18:35
