NAME

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

SYNOPSIS

       See Bio::Graphics::Panel and Bio::Graphics::Glyph.

DESCRIPTION

       This glyph draws "scored" features using a continuous color gradient is the HSV color
       space. The color of each segment is proportionate to the score.

OPTIONS

   Global glyph options:
       See Bio::Graphics::Glyph::generic

   Glyph-specific options:
       The color_map glyph recognizes the following glyph-specific options:

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

         -start_color Beginning of the color       white
                      gradient, expressed as a
                      named color or RGB hex
                      string

         -end_color   End of the color gradient    red

         -brightness  Color brilliance:  0-100     Calculated
                      This will override the
                      value from the named
                      color

         -saturation  Color saturation: 0-100      Calculated
                      This will override the
                      value from the named
                      color

         -pure_hue    Use the pure hue (bright-    0 (false)
                      ness and saturation both
                      at 100) for the named color

         -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    1 (true)
                      with the background color

       If max_score and min_score are not specified, the glyph will calculate the local maximum
       and minimum scores at run time.  If single features, unaggregated features, or multiple
       aggregates are being drawn, this will result in an inconsistent color scale.  It is
       recommended that global maximum and minimum scores be specified in the track
       configuration. Since many scoring functions are exponential, you may wish to take the log
       of your scores before passing them to this glyph.

   Color Gradients
       The color gradient is calculating by progressing along the rainbow spectrum from red to
       violet, also incrementing brightness and saturation, all proportate to the score value.
       To vary the hue only, "pure" hues can be used.  Pure hues have brightness and saturation
       values of 100. Some examples, in order, are red, yellow, lime, aqua/cyan, blue and
       magenta.  The gradient can progress in reverse orientation with the respect to the visible
       light spectrum if a lower-order color is used as the start and a higher order color used
       as the end (for example lime->red).

       Using the "pure_hue" option results in a brighter, more vibrant color spectrum, Choosing
       darker start and end colors, such as green or maroon, will result in a darker spectrum.  A
       single color spectrum can be created by using black or white as the start or end color.

       A grayscale spectrum will result if black and white are used as start and end colors.  One
       example of an effective visual heat map is to progress from white->red.

       For the start_color and end_color options, 140 named webcolors and their corresponding RGB
       hex codes (listed below) are supported.
