Creates a new scale "slot". Geoms added to a plot after this function will use a new scale definition.
new_scale(new_aes) new_scale_fill() new_scale_color() new_scale_colour()new_scale(new_aes) new_scale_fill() new_scale_color() new_scale_colour()
new_aes |
A string with the name of the aesthetic for which a new scale will be created. |
new_scale_color(), new_scale_colour() and new_scale_fill() are just
aliases to new_scale("color"), etc...
