Hello Anh Thu,

You can provide a callback for the glyph argument that returns different
glyphs depending on what you want to do (ie, how you've coded your
callback).  This example is from the perldoc for Bio::Graphics::Panel:

        $panel->add_track(\@exons,
                          -glyph => sub { my $feature = shift;
                                          $feature->source_tag eq ’curated’                                                    
                                                    ? ’ellipse’ : ’generic’; }
                         );
