  low = "#3B5FFF",
  mid = "#F7F7F7",
  high = "#FF3B30",
  midpoint = 0,
  oob = scales::squish
)

Arguments

...: Passed to ggplot2::scale_fill_gradient2().
limits: Scale limits.
low, mid, high: Endpoint and midpoint colours.

Examples

# Use the default PMV colour scale.
ggpsychro(tdb_lim = c(15, 35), hum_lim = c(0, 24)) +
    geom_comfort_pmv(contours = FALSE, labels = FALSE, n = c(45, 30)) +
    scale_fill_comfort_pmv(name = "PMV")


# Focus the legend on the usual comfort range.
ggpsychro(tdb_lim = c(15, 35), hum_lim = c(0, 24)) +
    geom_comfort_pmv(contours = FALSE, labels = FALSE, n = c(45, 30)) +
    scale_fill_comfort_pmv(limits = c(-1.5, 1.5), name = "PMV")


# Use a custom diverging palette.
ggpsychro(tdb_lim = c(15, 35), hum_lim = c(0, 24)) +
    geom_comfort_pmv(contours = FALSE, labels = FALSE, n = c(45, 30)) +
    scale_fill_comfort_pmv(
        low = "#2166AC",
        mid = "white",
        high = "#B2182B",
        name = "PMV"
