LinearWiggleDisplay

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

Draws quantitative signal as bars, points, a line or a color strip (span), for one source or many; rows: 'source' draws each source in a separate row.

Per-source metadata (a name, color and group for each) is preloaded on the adapter rather than here — see MultiWiggleAdapter's subadapters slot, where group drives the sidebar clustering tree and color sets each source's line or fill.

These are display-level slots: set them inside a track's displays to change its defaults (setting them at the track top level has no effect). The object shorthand displayDefaults: { key: value } is equivalent to the full displays: [{ type: 'LinearWiggleDisplay', displayId: '...', key: value }] array form — see configuring displays.

Example usage#

Minimal QuantitativeTrack config. See the quantitative track guide for all adapter and display options:

{
  type: 'QuantitativeTrack',
  trackId: 'coverage',
  name: 'Coverage',
  assemblyNames: ['hg38'],
  adapter: { type: 'BigWigAdapter', uri: 'https://example.com/coverage.bw' },
}

Several bigWigs, which a MultiQuantitativeTrack stacks one per row:

{
  type: 'MultiQuantitativeTrack',
  trackId: 'coverage_by_sample',
  name: 'Coverage by sample',
  assemblyNames: ['hg38'],
  adapter: {
    type: 'MultiWiggleAdapter',
    bigWigs: [
      'https://example.com/sample1.bw',
      'https://example.com/sample2.bw',
    ],
  },
}

Taller track, log scale, custom color:

{
  type: 'QuantitativeTrack',
  trackId: 'coverage',
  name: 'Coverage',
  assemblyNames: ['hg38'],
  adapter: { type: 'BigWigAdapter', uri: 'https://example.com/coverage.bw' },
  displayDefaults: {
    height: 200,
    encoding: {
      y: { scale: { type: 'log' } },
      color: { value: 'darkgreen' },
    },
  },
}

Config slots#

Display slots go on a display entry: "displays": [{ "type": "LinearWiggleDisplay", ... }], or in the track's displayDefaults when this is its default display. 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.

{
  "type": "LinearWiggleDisplay",
  "mark": "span"
}

{
  "type": "LinearWiggleDisplay",
  "rows": "source"
}

{
  "type": "LinearWiggleDisplay",
  "rowColor": { "scale": { "domain": ["tumor"], "range": ["#b2182b"] } }
}

{
  "type": "LinearWiggleDisplay",
  "encoding": { "color": { "scale": { "type": "threshold", "domain": [2] } } }
}

{
  "type": "LinearWiggleDisplay",
  "encoding": { "y": { "rules": [{ "value": 30, "label": "2 copies" }, 15] } }
}

Retired keys#

An older config may still write these. Each loads without an error, and jbrowse validate reports it as stale.
