`GeomVline`

Vertical reference-line alias. Canonicalized by normalize() to a rule layer. Annotation form: set params.xintercept. Data-driven form: map aes.x (inherited plot y is dropped so the one-axis rule contract holds).

Defaults

geom: vline
default stat: identity
default position: identity
params type: VlineParams

Alias

normalize() rewrites this geom to rule (with this alias's default stat and position). Prefer the canonical geom in new code.

Svelte component

import { GGPlot, GeomVline } from "@ggsvelte/svelte";

<GGPlot data={rows}>
  <GeomVline />
</GGPlot>

JSON layer

{
  "geom": "vline"
}
