The beeswarm geom is a convenient means to offset points within categories to reduce overplotting. Uses the beeswarm package
geom_beeswarm( mapping = NULL, data = NULL, stat = "identity", ..., method = "swarm", cex = 1, side = 0L, priority = "ascending", fast = TRUE, dodge.width = NULL, corral = "none", corral.width = 0.9, groupOnX = NULL, beeswarmArgs = list(), na.rm = FALSE, show.legend = NA, inherit.aes = TRUE )
Set of aesthetic mappings created by
aes(). If specified and
inherit.aes = TRUE (the default), it is combined with the default mapping
at the top level of the plot. You must supply
mapping if there is no plot
The data to be displayed in this layer. There are three options:

often aesthetics, used to set an aesthetic to a fixed value, like
colour = "red" or
size = 3. They may also be parameters
to the paired geom/stat.
Method for arranging points (see Details below)

Values between 1 (default) and 3 tend to work best.
Direction to perform jittering: 0: both directions; 1: to the right or upwards; -1: to the left or downwards.

NA, the default, includes if any aesthetics are mapped.
FALSE never includes, and
TRUE always includes.
It can also be a named logical vector to finely select the aesthetics to

rather than combining with them. This is most useful for helper functions
that define both data and aesthetics and shouldn't inherit behaviour from
the default plot specification, e.g.
ggplot2::qplot(class, hwy, data = ggplot2::mpg, geom='beeswarm') # Generate fake data distro <- data.frame( 'variable'=rep(c('runif','rnorm'),each=100), 'value'=c(runif(100, min=-3, max=3), rnorm(100)) ) ggplot2::qplot(variable, value, data = distro, geom='beeswarm') ggplot2::ggplot(distro,aes(variable, value)) + geom_beeswarm(priority='density',size=2.5)
