WiggleColor

Auto-generated from the config schema in the source — see the config guide for concepts. Provided by the wiggle plugin. View source.

Example usage

{ type: 'LinearWiggleDisplay', color: 'darkgreen' }
{
  type: 'LinearWiggleDisplay',
  color: { field: 'score', scale: 'threshold', domain: [2], range: ['#2166ac', '#b2182b'] },
}
{
  type: 'LinearWiggleDisplay',
  mark: 'span',
  color: { field: 'score', scale: 'linear', scheme: 'viridis' },
}

The quantitative display's color: one CSS color for every bar, or score through a scale. Through a threshold scale it is the bicolor plot — a color each side of one cut, the origin where the domain names none, and a color per band where it names more — and through linear a gradient across the y domain, through the y scale's own type, which colors each bar, point and density cell by its score. A line still parts in the gradient's two end colors. A subtrack's own color is rowColor's. A wiggle colors per signal rather than per feature, so a jexl: callback over a feature has nothing to read here.

Config slots

Slot types (fileLocation, frozen, ...) are explained in the config slot types reference. Slots a base configuration contributes are listed here too, so this table is the whole surface.

SlotDescription
value
maybeColor		One CSS color for every bar. Writing color: "darkgreen" lands here. Unset, the display paints the pos/neg pair about the origin, and several sources sharing one plot box each paint their row color.
field
maybeStringEnum (score)		score, the value each bar carries. Unset, the color paints value, or score while value is unset too, which jbrowse validate reads alike.
scale
maybeStringEnum (none, linear, threshold)		The scale from score to a color. threshold paints each band between two of its cuts, and on a density plot (mark: 'span') fades from white at the lowest cut to the first range color below it and the last above it; linear runs range, else scheme, else viridis across the y domain through scales.y.type, with domainMid at the middle stop, coloring each bar, point and density cell by its score, and a one-color range runs from white to that color; a line still parts in the two end colors. none paints value, keeping the field for a switch back. Unset beside the field, it is threshold.
domain
stringArray = []		for a threshold scale, up to eight cut points, sorted, empty meaning one at the origin
range
colorArray = []		a threshold scale's color for each band, lowest first, one more than the cuts, a missing middle band grey; a linear scale's stops, evenly spaced, one color meaning white to it
scheme
maybeStringEnum (viridis, magma, inferno, cividis, juicebox, fall, reds, blues, redblue, purpleorange, redgreyblue, blueyellowred)		a named ramp: a linear or log scale runs along it, and a threshold that writes cuts takes one color per interval from end to end; range's colors, where it lists any, win over it
reverse
boolean = false		turns the ramp round, so its last color paints the bottom of a linear or log domain or a threshold's lowest interval
domainMid
maybeNumber		the value the ramp's middle stop sits at, so a diverging ramp centres somewhere other than the middle of the domain, both sides on one scale: the farther end of the domain reaches its end color and equal distances from the middle take equal colors; unset, the stops are evenly spaced across it
labels
stringArray = []		key label for each domain value, one each in order, or under threshold for each interval from the lowest; one past the list keeps its own name
title
maybeString		key title; unset keeps the display's own heading, "" draws none
