Draw-key returning a small filled circle.

Used by point and jitter geoms.

Usage

draw-key-point()

Returns

Draw-key dictionary consumed by the legend renderer.

Examples

Force the point glyph in the legend (the default for points).

#let d = (
  (x: 1, y: 1, g: "a"),
  (x: 2, y: 2, g: "b"),
)
#plot(
  data: d,
  mapping: aes(x: "x", y: "y", fill: "g"),
  layers: (geom-point(size: 3pt, key: draw-key-point()),),
  width: 8cm,
  height: 5cm,
)

Use the point glyph on a layer that would otherwise default to a different shape, like a line layered over points.

#let d = (
  (x: 1, y: 1, g: "a"), (x: 2, y: 2, g: "a"),
  (x: 1, y: 3, g: "b"), (x: 2, y: 1, g: "b"),
)
#plot(
  data: d,
  mapping: aes(x: "x", y: "y", colour: "g"),
  layers: (geom-line(key: draw-key-point()),),
  width: 8cm,
  height: 5cm,
)
