  colour = NULL,
  alpha = 0.95,
  horizontal = FALSE
)

Arguments

An object of class orb_layer.

Examples

df <- data.frame(g = c("a", "b", "c"), v = c(3, 7, 5))
orb(df, x = g, y = v, fill = g) + orb_bars()
#> <orb_spec>
#>   data:   3 rows x 2 columns
#>   mapping: x, y, fill 
#>   layers:  bars
