Enum: MarkType

The cartesian primitive a grammar layer draws (heatmap is implied by a heatmap panel, not a mark).

Permissible Values

Value	Meaning	Description
line	None	Connected line (timeseries, bifurcation branch, trajectory)
scatter	None	Points (fixed points, special points, per-node profiles)
rule	None	Reference line at a value the layer’s output HOLDS (a threshold, a published …
band	None	Filled band between two series (an error band, a CI)
area	None	Series filled down to the baseline (a density/pdf, a cumulative share)
bar	None	Vertical bars, one per x (spectrum, per-category magnitude)

Slots

Name	Description
mark	Cartesian mark; omitted for heatmap panels (implied by the panel kind)

  line:
    text: line
    description: Connected line (timeseries, bifurcation branch, trajectory).
  scatter:
    text: scatter
    description: Points (fixed points, special points, per-node profiles).
  rule:
    text: rule
    description: 'Reference line at a value the layer''s output HOLDS (a threshold,
      a published number, an ensemble mean) — one line per value. The encoded channel
      picks the orientation: `x:` draws vertical, `y:` horizontal. Distinct from the
      `axvline`/`axhline` opts, which take a literal typed into the spec and are drawn
      as subdued gridlines.'
  band:
    text: band
    description: Filled band between two series (an error band, a CI). Its layer's
      output carries a length-2 axis beside the swept one, holding the two edges in
      ONE array — binding a lower edge and an upper edge as separate layers lets them
      come from different runs.
  area:
    text: area
    description: Series filled down to the baseline (a density/pdf, a cumulative share).
      Distinct from `band`, which spans two series, and from `bar`, which asserts
      the x values are discrete categories.
  bar:
    text: bar
    description: Vertical bars, one per x (spectrum, per-category magnitude). Distinct
      from `line` because a spectrum read as a line implies interpolation between
      mode numbers that do not exist.
