Chord diagram coordinate system — coord

Controls global rotation, aspect ratio, coordinate limits, clipping and the strategy used to fit chord geometry and labels.

Usage

coord_chord(
  rotation = 45,
  ratio = 1,
  xlim = NULL,
  ylim = NULL,
  expand = FALSE,
  clip = "off",
  fit = c("labels", "geometry", "manual")
)

Arguments

rotation: Global clockwise layout rotation in degrees, default 45.
ratio: Fixed y/x aspect ratio, default 1.
xlim, ylim: Optional user limits. Explicit limits take priority over automatically fitted limits.
expand: Logical. Expand coordinate limits, default FALSE. Automatic fitting already includes a small safety margin; set TRUE to request the additional ggplot2 coordinate expansion.
clip: Whether drawing is clipped to the panel, default "off".
fit: Fitting strategy: "labels" includes measured label boxes, "geometry" fits geometric elements only, and "manual" requires explicit xlim and ylim.

Value

A Coord object for ggplot2 + composition

Examples

library(ggchord)
data(seq_data_example)
p <- ggchord(seq_data_example) + coord_chord() + geom_seq()
#> Coordinate system already present.
#> ℹ Adding new coordinate system, which will replace the existing one.
