Bio::Graphics::Glyph::UseriContributed PerBio::Graphics::Glyph::hybrid_plot(3)NAMEBio::Graphics::Glyph::hybrid_plot - An xyplot plot drawing dual graph
using data from two wiggle files per track
SYNOPSIS
See <Bio::Graphics::Panel> <Bio::Graphics::Glyph> and
<Bio::Graphics::Glyph::wiggle_xyplot>.
DESCRIPTION
Note that for full functionality this glyph requires
Bio::Graphics::Glyph::generic (generic glyph is used for drawing
individual matches for small RNA alignments at a high zoom level,
specified by semantic zooming in GBrowse conf file) Unlike the regular
xyplot, this glyph draws two overlapping graphs using value data in
Bio::Graphics::Wiggle file format:

ID=Samlpe_2L;Name=Sample;Note=YourNoteHere;wigfileA=/datadir/track_001.2L.wig;wigfileB=/datadir/track_002.2L.wig
The "wigfileA" and "wigfileB" attributes give a relative or absolute
pathname to Bio::Graphics::Wiggle format files for two concurrent sets
of data. Basically, these wigfiles contain the data on signal intensity
(counts) for sequences aligned with genomic regions. In wigfileA these
data are additive, so for each sequence region the signal is calculated
as a sum of signals from overlapping matches (signal). In wigfileB the
signal represents the maximum value among all sequences (signal
quality) aligned with the current region so the user can see the
difference between accumulated signal from overlapping multiple matches
(which may likely be just a noise from products of degradation) and
high-quality signal from unique sequences.
It is essential that wigfile entries in gff file do not have score,
because score used to differentiate between data for dual graph and
data for matches (individual features visible at higher magnification).
After an update to wiggle_xyplot code colors for dual plot are now
hard-coded (blue for signal and orange for signal quality). Alpha
channel is also handled by wiggle_xyplot code now.
OPTIONS
In addition to some of the wiggle_xyplot glyph options, the following
options are recognized:
Name Value Description
--------------------
wigfileA path name Path to a Bio::Graphics::Wiggle file for accumulated vales in 10-base bins
wigfileB path name Path to a Bio::Graphics::Wiggle file for max values in 10-base bins
u_method method name Use method of [method name] to identify individual features (like alignment matches)
to show at high zoom level. By default it is set to 'match'
