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

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

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.

See Bio::Graphics::Glyph::generic

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.

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 corresponsing RGB hex codes (listed below) are supported.
