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.

OPTIONS

The following options are standard among all Glyphs. See Bio::Graphics::Glyph for a full explanation.

  Option      Description                      Default

  -do_gc      Whether to draw the GC      true
              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
