Add bars to a track

Description

Add bars to a track

Usage

spiral_bars(
  pos,
  value,
  baseline = get_track_data("ymin", track_index),
  bar_width = min(diff(pos)),
  gp = gpar(),
  track_index = current_track_index()
)

Arguments

pos	X-locations of the center of bars.
value	Height of bars. The value can be a simple numeric vector, or a matrix.
baseline	Baseline of the bars. Note it only works when value is a simple vector.
bar_width	Width of bars.
gp	Graphical parameters.
track_index	Index of the track.

Value

No value is returned.

Examples

x = seq(1, 1000, by = 1) - 0.5
y = runif(1000)
spiral_initialize(xlim = c(0, 1000))
spiral_track(height = 0.8)
spiral_bars(x, y)

# a three-column matrix
y = matrix(runif(3*1000), ncol = 3)
y = y/rowSums(y)
spiral_initialize(xlim = c(0, 1000))
spiral_track(height = 0.8)
spiral_bars(x, y, gp = gpar(fill = 2:4, col = NA))
