position_dodge

0th

Percentile

Adjust position by dodging overlaps to the side.

Adjust position by dodging overlaps to the side.

Usage
position_dodge(width = NULL, height = NULL)
Arguments
width
Manually specify width (does not affect all position adjustments)
height
Manually specify height (does not affect all position adjustments)

Other position adjustments: position_fill, position_identity, position_jitter, position_stack

Aliases
  • position_dodge
Examples
ggplot(mtcars, aes(x=factor(cyl), fill=factor(vs))) +
  geom_bar(position="dodge")
ggplot(diamonds, aes(x=price, fill=cut)) + geom_bar(position="dodge")
# see ?geom_boxplot and ?geom_bar for more examples

# Dodging things with different widths is tricky
df <- data.frame(x=c("a","a","b","b"), y=1:4, g = rep(1:2, 2))
(p <- qplot(x, y, data=df, group=g, position="dodge", geom="bar",
  stat="identity"))

p + geom_linerange(aes(ymin = y-1, ymax = y+1), position="dodge")
# You need to explicitly specify the width for dodging
p + geom_linerange(aes(ymin = y-1, ymax = y+1),
  position = position_dodge(width = 0.9))

# Similarly with error bars:
p + geom_errorbar(aes(ymin = y-1, ymax = y+1), width = 0.2,
  position="dodge")
p + geom_errorbar(aes(ymin = y-1, ymax = y+1, width = 0.2),
  position = position_dodge(width = 0.90))
