200 | Starting height in pixels for the genotype rows; drag-resizable, and the rows divide it while row height is on auto-fit |
| **showInsertionGlyphs**true | Widen each alt-carrying cell of an insertion to a marker sized by the inserted bp, the same one `plugins/alignments` and `plugins/maf` draw, with the bp count when the row is tall enough.false | Draw a `LinearVariantDisplay`-style lane above the genotype rows: one mark per record at its genomic span, colored by whatever "Color by → Cells" is set to. It answers "which variant am I looking at" without a second track, the relationship the coverage band has to a pileup — `shared/variantTopBands.ts` holds the band stack.40 | Height of the variant lane, spent only while `showVariantLane` is on. On the config rather than a prop for the same reason `height` and `lineZoneHeight` are: a drag-resize outlives the display instance, so unticking and reticking the track keeps the lane the user sized.'auto' | Letter the lane's marks with each record's VCF ID and/or its description, in plugin-canvas's label font at its measured widths and in its two colors — the same text a `LinearVariantDisplay` puts under the same record, under the same enum it spells the choice with.false | Starting value for drawing reference alleles. When false, the row background is filled solid grey and only ALT alleles are painted on top (makes overlapping variants easier to see); when true, reference alleles are drawn normally. Seeds referenceDrawingMode the first time a config is loaded. |
| **lineZoneHeight**0 | Height of the zone above the rows holding the lines that tie each matrix column to its genomic position. 0 (the default here) means no zone at all — only the matrix display, which lays columns out by feature index rather than at their genomic positions, raises it.false | Draw a hairline between adjacent sample rows. Off by default, and only drawn once rows are at least 4px tall — below that the line is as thick as the row it borders. |
| **showTooltips**true | Show the hover tooltip naming the genotype, the sample and the record under the pointer. On by default; turning it off leaves every other hover affordance — the crosshairs, the highlighted cell, the cross-display `session.hovered` channel — alone, so the pointer still says where it is while the panel stops covering the rows beside it.'alleleCount' | 'alleleCount' draws one row per sample colored by allele dosage; 'phased' draws one row per haplotype |
| **featureColor**'' | Optional per-feature color for the genotype cells: a jexl expression (or plain CSS color) evaluated once per variant in the worker, painting every alt-carrying cell with that color while ref/no-call cells keep their normal coloring so "who carries it" still reads. Empty means the default genotype-based coloring (allele dosage / phasing). The "Color by..." menu offers presets like consequence impact (`jexl:impactColor(feature)`), but any feature jexl works, same as the standard `color` slot. |
| **minorAlleleFrequencyFilter**0 | Hide variants whose minor allele frequency is below this threshold1 | Hide variants whose fraction of no-call (missing) genotypes is above this threshold; 1 keeps every varianttrue _promotable_ | Whether to draw the floating legend over the display. It is clipped to the display's own bounds, so while it is on it sets a floor under the lane height: turn it off to size a short lane to its rows rather than to its key, which is what a one-record SV call genotyped across a handful of carriers wants. |
| **colorBy**'' | Name of a sample-metadata attribute (a column in the adapter's samplesTsvLocation, e.g. 'population') to color the sidebar rows by; empty means no grouping |
| **groupBy**'' | Name of a sample-metadata attribute (a column in the adapter's samplesTsvLocation, e.g. 'population') to order the sample rows by, so each group's rows are contiguous and a group-restricted genotype pattern reads as one band; empty means the rows keep their existing order |
| **referenceDrawingMode**'skip' | A 'draw'/'skip' toggle for reference alleles, settable independent of showReferenceAlleles (the admin-config-only starting default). No fallback derivation at read time — preProcessSnapshot below seeds this from showReferenceAlleles once, the first time a config lacking it is hydrated, so from then on this slot alone is the single source of truth. |
| **rowHeight**0 | per-row height in px, scrolling the rows that do not fit; 0 (the default) fits the rows to the display height instead, dividing it between them |
| **showTree**true | Show the sample clustering tree in the sidebar |
| **showBranchLength**true | position tree nodes by branch length (dendrogram) rather than evenly by topology (cladogram) |
| **showRowLabels**true | Show the per-sample row labels in the sidebar |
| Inherited from [BaseLinearDisplay](../baselineardisplay) | 5 slots |
| **maxFeatureScreenDensity**1 | maximum features per pixel before showing a "too many features" message[] | config jexlFilters are deferred evaluated so they are prepended with jexl at runtime rather than being stored with jexl in the config |
| **fetchSizeLimit**1_000_000 | maximum data to attempt to download for a given track, used if adapter doesn't specify onefalse | Declarative equivalent of the "Force load" button on the "too much data" banner: when true the display always renders, however large the region or dense the features. Off by default (the gate guards against huge downloads). Set it on a view no one can interact with — an embedded / notebook view, or a screenshot — where the region is known and you want it drawn without a click.
