scale-size-identity

Size scale that uses each row’s value as the marker or line size.

Values may be Typst lengths (passed through verbatim) or numbers (interpreted as point sizes). No legend is drawn because the column carries the visual outcome verbatim.

Usage

scale-size-identity(
  name: none,
)

Parameters

Parameter	Default	Description
name	none	Legend title. Identity scales draw no legend.

Returns

Scale object consumed by plot.

Examples

Per-row Typst lengths carried straight through to the marker radii; no legend is drawn.

#let d = (
  (x: 1, y: 1, s: 2pt),
  (x: 2, y: 2, s: 5pt),
  (x: 3, y: 3, s: 9pt),
)
#plot(
  data: d,
  mapping: aes(x: "x", y: "y", size: "s"),
  layers: (geom-point(),),
  scales: (scale-size-identity(),),
  width: 10cm,
  height: 6cm,
)
