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.
