scale-y-sqrt
Continuous y scale on a square-root axis.
Thin wrapper over scale-y-continuous with transform: "sqrt". All y values must be non-negative.
Usage
scale-y-sqrt(
name: none,
limits: none,
breaks: auto,
labels: auto,
)Parameters
| Parameter | Default | Description |
|---|---|---|
name |
none |
Axis title. Overrides any name set via labs when both are present. |
limits |
none |
Pair (lo, hi) clipping the trained domain, or none for automatic limits. |
breaks |
auto |
Array of break values, or auto for automatic tick selection. |
labels |
auto |
Array of tick labels aligned with breaks, or auto. |
Returns
Scale object consumed by plot.
Examples
Square-root y axis straightens a quadratic relationship.
#let d = range(0, 11).map(i => (x: i, y: i * i))
#plot(
data: d,
mapping: aes(x: "x", y: "y"),
layers: (geom-point(size: 2pt),),
scales: (scale-y-sqrt(name: "y"),),
width: 10cm,
height: 6cm,
)
Combine with limits to highlight a specific range without changing the underlying data.
#let d = range(0, 11).map(i => (x: i, y: i * i))
#plot(
data: d,
mapping: aes(x: "x", y: "y"),
layers: (geom-point(size: 2pt),),
scales: (scale-y-sqrt(name: "y", limits: (0, 64)),),
width: 10cm,
height: 6cm,
)
