geom_lode | R Documentation |
geom_alluvium
receives a dataset of the horizontal (x
) and vertical (y
,
ymin
, ymax
) positions of the lodes of an alluvial plot, the
intersections of the alluvia with the strata. It plots rectangles for these
lodes of a provided width
.

Set of aesthetic mappings created by |
data |
The data to be displayed in this layer. There are three options: If A A |
stat |
The statistical transformation to use on the data; override the default. |
position |
Position adjustment, either as a string naming the adjustment
(e.g. |
width |
Numeric; the width of each stratum, as a proportion of the distance between axes. Defaults to 1/3. |

Additional arguments passed to |
geom_alluvium
, geom_flow
, geom_lode
, and geom_stratum
understand the
following aesthetics (required aesthetics are in bold):
x
y
ymin
ymax
alpha
colour
fill
linetype
size

group
is used internally; arguments are ignored.
Alluvium, flow, and lode geoms default to alpha = 0.5
. Learn more about
setting these aesthetics in vignette("ggplot2-specs", package = "ggplot2")
.
The previously defunct parameters axis_width
and ribbon_bend
have been
discontinued. Use width
and knot.pos
instead.
ggplot2::layer()
for additional arguments and
stat_alluvium()
and
stat_stratum()
for the corresponding stats.
