geom_ribbon {ggplot2}R Documentation

geom_ribbon

Description

Ribbons, y range with continuous x values

Usage

geom_ribbon(mapping=NULL, data=NULL, stat="identity", position="identity", ...)

Arguments

mapping mapping between variables and aesthetics generated by aes
data dataset used in this layer, if not specified uses plot dataset
stat statistic used by this layer
position position adjustment used by this layer
... ignored

Details

This page describes geom_ribbon, see layer and qplot for how to create a complete plot from individual components.

Value

A layer

Aesthetics

The following aesthetics can be used with geom_ribbon. Aesthetics are mapped to variables in the data with the aes function: geom\_ribbon(\code{aes}(x = var))

Examples

## Not run: 
# Generate data
huron <- data.frame(year = 1875:1972, level = as.vector(LakeHuron))
huron$decade <- round_any(huron$year, 10, floor)

h <- ggplot(huron, aes(x=year))

h + geom_ribbon(aes(ymin=0, ymax=level))
h + geom_area(aes(y = level))

# Add aesthetic mappings
h + geom_ribbon(aes(ymin=level-1, ymax=level+1))
h + geom_ribbon(aes(ymin=level-1, ymax=level+1)) + geom_line(aes(y=level))

# Another data set, with multiple y's for each x
m <- ggplot(movies, aes(y=votes, x=year)) 
(m <- m + geom_point())

# The default summary isn't that useful
m + stat_summary(geom="ribbon", fun.ymin="min", fun.ymax="max")
m + stat_summary(geom="ribbon", fun.data="median_hilow")

# Use qplot instead
qplot(year, level, data=huron, geom=c("area", "line"))
