Get the chord layout from the package environment

Returns the most recently computed chord layout (after the plot was built, e.g. via print() or ggplot_build()). This is useful for building custom layers or annotations on top of the chord geometry.

Usage

get_chord_layout(plot = NULL, build = TRUE)

Arguments

plot

Optional ggchord plot. Supplying the plot is the reliable way to retrieve its own layout when several plots are built in one session.

build

Logical. Build the layout when it is not cached, default TRUE.

Value

A chord layout list containing the computed geometry (sequence arcs, ribbon polygons, gene arrows, axis elements, extremes, colors, etc.)

Examples

library(ggchord)
data(seq_data_example)
data(ribbon_data_example)
p <- ggchord(seq_data_example, ribbon_data_example) + geom_seq() + geom_ribbon()
invisible(ggplot2::ggplot_build(p))
names(get_chord_layout(p)$seq_arcs)
#> NULL
