Bio::Graphics::Glyph::UserlContributed)Bio::Graphics::Glyph::wiggle_density(3)

NAME
       Bio::Graphics::Glyph::wiggle_density - A density plot compatible with
       dense "wig"data

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

DESCRIPTION
       This glyph works like the regular density but takes value data in
       Bio::Graphics::Wiggle file format:

	reference = chr1
	ChipCHIP Feature1 1..10000 wigfile=./test.wig;wigstart=0
	ChipCHIP Feature2 10001..20000 wigfile=./test.wig;wigstart=656
	ChipCHIP Feature3 25001..35000 wigfile=./test.wig;wigstart=1312

       The "wigfile" attribute gives a relative or absolute pathname to a
       Bio::Graphics::Wiggle format file. The optional "wigstart" option gives
       the offset to the start of the data. If not specified, a linear search
       will be used to find the data. The data consist of a packed binary
       representation of the values in the feature, using a constant step such
       as present in tiling array data.

   OPTIONS
       The same as the regular graded_segments glyph, except that the
       following options are recognized:

	  Name	      Value	   Description
	  ----	      -----	   -----------

	  basedir     path	   Path to be used to resolve "wigfile" and "densefile"
				       tags giving relative paths. Default is to use the
				       current working directory. Absolute wigfile &
				       densefile paths will not be changed.

	  autoscale   "local" or "global"
				    If one or more of min_score and max_score options
				    are absent, then these values will be calculated
				    automatically. The "autoscale" option controls how
				    the calculation is done. The "local" value will
				    scale values according to the minimum and maximum
				    values present in the window being graphed. "global"
				    will use chromosome-wide statistics for the entire
				    wiggle or dense file to find min and max values.

	  smoothing   method name  Smoothing method: one of "mean", "max", "min" or "none"

	  smoothing_window
		      integer	   Number of values across which data should be smoothed.

	  bicolor_pivot
		      name	   Where to pivot the two colors when drawing bicolor plots.
				      Options are "mean" and "zero". A numeric value can
				      also be provided.

	  pos_color   color	   When drawing bicolor plots, the fill color to use for values
				     that are above the pivot point.

	  neg_color   color	   When drawing bicolor plots, the fill color to use for values
				     that are below the pivot point.

   SPECIAL FEATURE TAGS
       The glyph expects one or more of the following tags (attributes) in
       feature it renders:

	  Name	      Value	   Description
	  ----	      -----	   -----------

	  wigfile     path name	   Path to the Bio::Graphics::Wiggle file for vales.
				   (required)

	  densefile   path name	   Path to a Bio::Graphics::DenseFeature object
				      (deprecated)

	  denseoffset integer	   Integer offset to where the data begins in the
				      Bio::Graphics::DenseFeature file (deprecated)

	  densesize   integer	   Integer size of the data in the Bio::Graphics::DenseFeature
				      file (deprecated)
