theme_kodom_circular: Theme for circular ggkodom plots

In ggkodom: Visualize Individual Longitudinal Trajectories

Theme for circular ggkodom plots

Description

Fully minimal Cartesian theme for geom_kodom_circular(): no axis text, ticks, or grid lines. Reference rings are drawn by the geom itself as annotation layers, so this theme suppresses all panel grid elements.

Usage

theme_kodom_circular(base_size = 12)

Arguments

base_size

Base font size (default 12).

Details

Unlike the original coord_polar()-based approach, geom_kodom_circular() performs its coordinate transformation inside the stat and renders in ordinary Cartesian space. This means panel.grid.major.y lines would appear as horizontal rules, not concentric circles — so both major axes are suppressed here.

Value

A ggplot2::theme() object.

Examples

library(ggplot2)
df <- data.frame(
  subject_id = rep(1:5, each = 4),
  time = rep(1:4, 5),
  visit_month = rep(1:4, 5),
  value = rep(1:4, 5),
  hba1c = rep(1:4, 5),
  arm = rep(c("Treatment", "Control"), c(12, 8))
)
ggplot(df, aes(x = time, id = subject_id, colour = value)) +
  geom_kodom_circular() +
  scale_colour_kodom() +
  coord_fixed() +
  theme_kodom_circular()
