[Bioperl-l] setting a strand in Bio::Graphics

[Emanuele Osimo]

Hello,
I've tried all the arrows suggested in
http://search.cpan.org/~lds/Bio-Graphics-1.982/lib/Bio/Graphics/Glyph/arrow.pm,
but I can't figure out how to tell in the options of $panel->add_track the
strand of the feature I'm adding.
I'm drawing DNA elements from a local DB, and I have a field "strand" which
can be + or -.
Please help!
