Good afternoon all,

I joined the mailing list hoping for some suggestions with a problem I'm having.  I've previously used xymatrix, but for a paper I'm working on I need the ability to put lines with arrows at arbitrary locations in x-y space.  In the following MWE I specified two points and then drew a line between them. From the xy-pic reference manual I used `?>*' to combine two commands and then tried to add an arrow head to the end of my line.




That just drops the ‘>’ character, not an arrowhead.

Instead try


or simply   "A";"B"**@{.>}

Try also the effect of:    "A";"B"**@{>.>} or   "A";"B"**@{(.>}



From the MWE the arrow head appears but it is not in the same direction as the line.  I would appreciate any assistance the group could offer.

Thank you,
