  name = ggplot2::waiver(),
  trans = "discrete",
  limits = NULL,
  range = NULL,
  breaks = NULL,
  labels = NULL,
  ...
)

plot: A plotit object.
name: Scale title (legend name).
trans: Scale transformation. Default "discrete". Allowed: "discrete", "reverse". "identity" and "binned" are rejected with targeted error messages.
