NAME

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

SYNOPSIS

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

DESCRIPTION

This is identical to the "alignment" glyph, and is used for drawing features that consist of discontinuous segments. The color intensity of each segment is proportionate to the score.

OPTIONS

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

Option      Description                      Default
------      -----------                      -------

-fgcolor      Foreground color	       black

-outlinecolor	Synonym for -fgcolor

-bgcolor      Background color               turquoise

-fillcolor    Synonym for -bgcolor

-linewidth    Line width                     1

-height       Height of glyph		       10

-font         Glyph font		       gdSmallFont

-connector    Connector type                 0 (false)

-connector_color
              Connector color                black

-label        Whether to draw a label	       0 (false)

-description  Whether to draw a description  0 (false)

-hilite       Highlight color                undef (no color)

In addition, the alignment glyph recognizes the following glyph-specific options:

Option      Description                   Default
------      -----------                   -------

-max_score  Maximum value of the	    Calculated
            feature's "score" attribute

-min_score  Minimum value of the          Calculated
            feature's "score" attribute

-vary_fg    Vary the foreground color as  0 (false)
            well as the background

If max_score and min_score are not specified, then the glyph will calculate the local maximum and minimum scores at run time. Since many scoring functions are exponential you may wish to take the log of your scores before passing them to this glyph.

BUGS

Please report them.
