NAME

Bio::Graphics::Glyph::dna - The "dna" glyph

SYNOPSIS

See L<Bio::Graphics::Panel> and L<Bio::Graphics::Glyph>.

DESCRIPTION

This glyph draws DNA sequences. At high magnifications, this glyph will draw the actual base pairs of the sequence (both strands). At low magnifications, the glyph will plot the GC content.

For this glyph to work, the feature must return a DNA sequence string in response to the dna() method.

            graph at low mags

-gc_bins    Fixed number of intervals   100
            to sample across the
            panel.

-axis_color Color of the vertical axes  fgcolor
            in the GC content graph

-strand      Show both forward and      auto
            reverse strand, one of
            "forward", "reverse",
            "both" or "auto".
            In "auto" mode,
            +1 strand features will
            show the plus strand
            -1 strand features will
            show the reverse complement
            and strandless features will
            show both
