How to Jitter Points in ggplot2 (With Examples) - Statology How to Jitter Points in ggplot2 (With Examples) When creating a scatter plot, it can be helpful to jitter the points so that it's easier to view points that may be overlapping. The easiest way to jitter points in ggplot2 is to use geom_jitter (), which uses the following basic syntax: ggplot (df, aes (x=x, y=y)) + geom_jitter () ggplot2.tidyverse.org › referenceFunction reference • ggplot2 All ggplot2 plots begin with a call to ggplot(), supplying default data and aesthethic mappings, specified by aes(). You then add layers, scales, coords and facets with + . To save a plot to disk, use ggsave() .
