geom-linerange
Linerange layer: one vertical line from ymin to ymax at each x.
Mapping must provide x, ymin, ymax. Colour and linetype may be mapped or set as fixed layer parameters.
Usage
geom-linerange(
mapping: none,
data: none,
stroke: 0.8pt,
colour: auto,
alpha: auto,
linetype: "solid",
stat: "identity",
position: "identity",
inherit-aes: true,
)Parameters
| Parameter | Default | Description |
|---|---|---|
mapping |
none |
Layer-specific aesthetic mapping built with aes. Must map x, ymin, ymax. |
data |
none |
Layer-specific dataset. Falls back to the plot data when none. |
stroke |
0.8pt |
Line thickness (a Typst length). |
colour |
auto |
Fixed line colour. auto resolves via the colour scale. |
alpha |
auto |
Line opacity in [0, 1]. |
linetype |
"solid" |
Dash keyword. Defaults to "solid". |
stat |
"identity" |
Statistical transform name. Usually "identity". |
position |
"identity" |
Position adjustment name. Usually "identity". |
inherit-aes |
true |
Whether to merge the plot-level mapping into this layer’s mapping. |
Returns
Layer dictionary consumed by plot.
Examples
Bare vertical ranges, no end caps.
#let d = range(1, 6).map(i => (
x: i,
lo: i - 0.5,
hi: i + 0.5,
))
#plot(
data: d,
mapping: aes(x: "x", ymin: "lo", ymax: "hi"),
layers: (geom-linerange(stroke: 1pt),),
width: 10cm,
height: 6cm,
)
Map colour to a categorical column to differentiate ranges per group.
#let d = range(1, 6).map(i => (
x: i, lo: i - 0.5, hi: i + 0.5,
k: if calc.rem(i, 2) == 0 { "even" } else { "odd" },
))
#plot(
data: d,
mapping: aes(x: "x", ymin: "lo", ymax: "hi", colour: "k"),
layers: (geom-linerange(stroke: 1.2pt),),
width: 10cm,
height: 6cm,
)
