One density curve per group, offset vertically so distributions can be
compared at a glance. Groups are ordered by their factor levels, first
level at the bottom.
geom_ridgeline(
mapping = NULL,
data = NULL,
scale = 1.6,
color = NULL,
alpha = NULL,
linewidth = NULL,
bw = NULL
)
Arguments
- mapping, data
Standard layer overrides. Map the value to x and
the group to y (or color).
- scale
Height of each ridge as a multiple of the row spacing;
values above 1 make ridges overlap.
- color, alpha, linewidth
Appearance.
- bw
Density bandwidth; NULL uses a Silverman rule of thumb.
Value
A Layer to add with +.
Examples
ggnext(iris, aes(Sepal.Length, Species)) + geom_ridgeline()
#> <ggnext plot>
#> data: 150 x 5
#> aes: x = Sepal.Length, y = Species
#> layers: 1
#> coord: cartesian
#> mode: static
