Omni baseline axis line (non-bar/column charts only)

Draws the light navy baseline next to the category labels, spanning only the data rows (not the full panel height). Omit on bar/column charts, where the bars already begin at the labels.

Usage

omni_baseline(n, orientation = c("vertical", "horizontal"), at = 0, pad = 0.3)

Arguments

n

Number of categories on the categorical axis.

orientation

`"vertical"` line (horizontal charts) or `"horizontal"` (vertical charts).

at

Baseline position on the value axis (usually 0).

pad

Extension beyond the first/last category center.

Value

A single `annotate("segment", ...)` layer.

Examples

library(ggplot2)
ggplot(mtcars, aes(mpg, factor(cyl))) +
  geom_point() +
  omni_baseline(n = 3)
