Size scale — scale_size • plotit

Maps data values to point/line sizes.

Usage

scale_size(
  plot,
  name = ggplot2::waiver(),
  trans = NULL,
  limits = NULL,
  range = NULL,
  breaks = NULL,
  labels = NULL,
  ...
)

plot: A plotit object.
name: Scale title (legend name).
trans: Scale transformation. NULL auto-detects, otherwise one of: "identity", "discrete", "reverse", "binned". Unsupported values (e.g. "log") produce a targeted error message.
limits: Data domain.
range: Output size range as c(min, max). NULL = default c(1, 6). Only meaningful for continuous scales (ignored for discrete/binned).
breaks: Legend key positions.
labels: Legend key labels.
...: Passed to the underlying ggplot2 scale function.

A modified plotit object.
