Scale.color_discrete_hue

Create a discrete color scale to be used for the plot. Scale.discrete_color is an alias for Scale.color_discrete_hue.

Arguments

• levels (optional): Explicitly set levels used by the scale. Order is respected.

• order (optional): A vector of integers giving a permutation of the levels default order.

Examples

This forces the use of a discrete scale on data that would otherwise receive a continuous scale:

plot(x=rand(12), y=rand(12), color=repeat([1,2,3], outer=[4]),
     Scale.color_discrete())
