Draw axis along the spiral

spiral_axis(
  h = c("top", "bottom"),
  at = NULL,
  major_at = at,
  labels = TRUE,
  curved_labels = FALSE,
  minor_ticks = 4,
  major_ticks_length = unit(4, "bigpts"),
  minor_ticks_length = unit(2, "bigpts"),
  ticks_gp = gpar(),
  labels_gp = gpar(fontsize = 6),
  track_index = current_track_index()
)

spiral_xaxis(...)

Arguments

h: Position of the axis. The value can be a character of "top" or "bottom".
at: Breaks points on axis.
major_at: Breaks points on axis. It is the same as at.
labels: The corresponding labels for the break points.
curved_labels: Whether are the labels are curved?
minor_ticks: Number of minor ticks.
major_ticks_length: Length of the major ticks. The value should be a grid::unit() object.
minor_ticks_length: Length of the minor ticks. The value should be a grid::unit() object.
ticks_gp: Graphical parameters for the ticks.
labels_gp: Graphical parameters for the labels.
track_index: Index of the track.
...: All pass to spiral_axis().

Value

No value is returned.

Examples

spiral_initialize()
spiral_track()
spiral_axis()


# if the spiral is interpolated by the curve length
spiral_initialize(scale_by = "curve_length"); spiral_track()
spiral_axis()


spiral_initialize(xlim = c(0, 360*4), start = 360, end = 360*5); spiral_track()
spiral_axis(major_at = seq(0, 360*4, by = 30))


spiral_initialize(xlim = c(0, 12*4), start = 360, end = 360*5); spiral_track()
spiral_axis(major_at = seq(0, 12*4, by = 1), labels = c("", rep(month.name, 4)))
