Math & Science ⇒ centred xy-pic diagram with fleqn

[lauraf]

Hi all,

I am using the amsmath package with the fleqn option. This causes diagrams I have drawn with xy-pic to also be left-aligned, whereas I would like them centred.

For example:

Code: Select all

\documentclass{article}

\usepackage[all]{xy}

\usepackage[fleqn]{amsmath}


\begin{document}

\begin{displaymath}
\xymatrix{ 
{\bullet} \ar@{--}[d]\ar@{=}[dr]\ar@{-}[r] 
& {\bullet} \ar@{.}[d] \\ 
{\bullet} & {\bullet} \ar[l] }
\end{displaymath}

\end{document}

Is there any way to override fleqn? Or how else can I achieve this, i.e. left-aligned equations but centred diagrams?

Many thanks!
Laura

Hi Laura,

you could use flalign*:

Code: Select all

\begin{flalign*}
    && \xymatrix{ ... } &&
\end{flalign*}
