Binned position scales

scale_x_binned() / scale_y_binned() cut a continuous position variable into bins: axis ticks fall at the bin boundaries and each datum is drawn at its bin centre. Breaks use the same classification as the binned colour scales (style/n; classInt for jenks/fisher/… — a Suggest). Handy to summarise a dense continuous axis, or to place mark_bar() on a binned continuous x.

Usage

scale_x_binned(
  plot,
  style = "pretty",
  n = 10,
  breaks = NULL,
  labels = NULL,
  name = NULL
)

scale_y_binned(
  plot,
  style = "pretty",
  n = 10,
  breaks = NULL,
  labels = NULL,
  name = NULL
)

Arguments

plot

A PlotSpec.

style

Binning style: "pretty" (default), "equal", "quantile", or a classInt style.

n

Target number of bins.

breaks

Explicit bin boundaries (overrides style/n), or NULL.

labels

Explicit boundary labels, or NULL to format the boundaries.

name

Axis title, or NULL to derive from the encoding.

Value

The modified PlotSpec.

Examples

vplot(mtcars) |> mark_point(x = wt, y = mpg) |> scale_x_binned(n = 6)
