text style. You may change this by redefinining the macro
<code>\objectstyle</code>, and the label style by redefining
<code>\labelstyle</code>. We can combine this with the
above to get "small diagrams," <I>e.g.</I>, typing
<BLOCKQUOTE><PRE>$\left(
\def\objectstyle{\scriptstyle}
\def\labelstyle{\scriptstyle}
\vcenter{\xymatrix @-1.2pc @ur {
A \ar[r]^{a} & B \ar[d]^{b} \\
A'\ar[u]^{a'} & B'\ar[l]^{b'} }}
\right)$</PRE></BLOCKQUOTE>
in a paragraph will typeset "<IMG WIDTH=124 HEIGHT=95 ALIGN=BOTTOM ALT="tex2html_wrap2758" SRC="img66.gif">."
<P>
You can even abandon the use of math mode entirely: the command
<code>\def</code> <code>\objectstyle</code> <code>{\hbox}</code> will change the format of entries to
plain text.
<P>
Similarly, all entries are rectangular by default, but it is possible
to change this to <em>round</em> by
declaring the default <em>modifiers</em> to be applied to all entries that do
not override them (<I>cf.</I> section <A HREF="node13.html#arrowsobjects">2.2</A>):
<BLOCKQUOTE><PRE>\entrymodifiers={++[o][F-]}
\SelectTips{cm}{}
\xymatrix @-1pc {
*\txt{start} \ar[r]
& 0 \ar@(r,u)[]^b \ar[r]_a
& 1 \ar[r]^b \ar@(r,d)[]_a
& 2 \ar[r]^b
\ar `dr_l[l] `_ur[l] _a [l]
&*++[o][F=]{3}
\ar `ur^l[lll]`^dr[lll]^b [lll]
\ar `dr_l[ll] `_ur[ll] [ll] }</PRE></BLOCKQUOTE>
will typeset
<P><CENTER><BR><IMG WIDTH=287 HEIGHT=94 ALIGN=BOTTOM ALT="displaymath1080" SRC="img67.gif"><BR></CENTER><P>
Notice how we obtain the double ring using the <code>*</code><em>object</em>
form which then has to include all the desired modifiers (and how the
use of computer modern tips is nice for diagrams as these).
