Scales for point aesthetics

These are various scales that can be applied to point aesthetics, such as point_color, point_fill, point_size. The individual scales all have the same usage as existing standard ggplot2 scales, only the name differs.

See scale_vline_color_hue() for specific scales for vline 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)) +
  geom_density_ridges(
    aes(
      point_color = Species, point_fill = Species,
      point_shape = Species
    ),
    alpha = .4, jittered_points = TRUE
  ) +
  theme_ridges()
#> Picking joint bandwidth of 0.181

# modified scales
ggplot(iris, aes(x=Sepal.Length, y=Species, fill = Species)) +
  geom_density_ridges(
    aes(
      point_color = Species, point_fill = Species,
      point_shape = Species
    ),
    alpha = .4, point_alpha = 1,
    jittered_points = TRUE
  ) +
  scale_fill_hue(l = 50) +
  scale_point_color_hue(l = 20) +
  scale_point_fill_hue(l = 70) +
  scale_discrete_manual("point_shape", values = c(21, 22, 23)) +
  theme_ridges()
