Lollipop geom for event metric visualisation

Source: R/geom_lolli3.R
geom_lolli3.Rd

A ggplot2 geom that draws lollipop (stem + point) plots for event metrics.

Usage

geom_lolli3(
  mapping = NULL,
  data = NULL,
  stat = "identity",
  position = "identity",
  ...,
  na.rm = FALSE,
  show.legend = NA,
  inherit.aes = TRUE
)

Arguments

mapping

Aesthetic mappings. Requires x and y.

data

The data to display.

stat

Statistical transformation. Default "identity".

position

Position adjustment. Default "identity".

...

Additional arguments.

na.rm

Remove NAs? Default FALSE.

show.legend

Show legend? Default NA.

inherit.aes

Inherit aesthetics? Default TRUE.

Value

A ggplot2 layer.

Details

Each lollipop is drawn independently from its own row – unlike geom_flame3, nothing here depends on row order or grouping within a series. For depth-resolved data, map depth to colour (or shape) to distinguish levels, or use ggplot2::facet_wrap(~ depth); both work with the standard ggplot2 aesthetics and need no special handling from this geom.

Examples

library(ggplot2)
df <- data.frame(x = as.Date("2020-01-01") + seq(0, 300, by = 30),
                 y = c(1.2, 2.1, 0.8, 3.5, 1.9, 2.7, 0.5, 1.1, 2.3, 1.6, 0.9))
ggplot(df, aes(x = x, y = y)) + geom_lolli3()
