Scales for vline aesthetics

These are various scales that can be applied to vline aesthetics, such as vline_color, vline_width, vline_linetype. The individual scales all have the same usage as existing standard ggplot2 scales, only the name differs.

See scale_point_color_hue() for specific scales for point aesthetics and scale_discrete_manual() for a general discrete scale.

Examples

library(ggplot2)

# default scales
ggplot(iris, aes(x=Sepal.Length, y=Species, fill = Species, color = Species)) +
  geom_density_ridges(
    aes(vline_color = Species, vline_linetype = Species),
    alpha = .4, quantile_lines = TRUE
  ) +
  theme_ridges()
#> Picking joint bandwidth of 0.181


# modified scales
ggplot(iris, aes(x=Sepal.Length, y=Species, fill = Species, color = Species)) +
  geom_density_ridges(
    aes(vline_color = Species),
    alpha = .4, quantile_lines = TRUE
  ) +
  scale_fill_hue(l = 50) +
  scale_vline_color_hue(l = 30) +
  theme_ridges()
