Julia doesn't register the existence of ColoredPoints?

[alexdarling]

I saw that ColoredPoints was a part of the Winston package and tried to make a plot with it, but Julia seems to not register its existence?

julia> Points
Points (constructor with 2 methods)

julia> ColoredPoints
UndefVarError(:ColoredPoints)

I checked Wiston.jl and nothing looks out of order.

type ColoredPoints <: SymbolDataComponent
    attr::PlotAttributes
    x
    y
    s
    c

    function ColoredPoints(x, y, s, c, args...; kvs...)
        self = new(Dict())
        iniattr(self)
        kw_init(self, args...; kvs...)
        self.x = x
        self.y = y
        self.s = s
        self.c = c
        self
    end
end

kw_defaults(::ColoredPoints) = @Dict(
    :symbolkind => config_value("Points","symbolkind"),
    :symbolsize => config_value("Points","symbolsize"),
)

limits(self::ColoredPoints, window::BoundingBox) =
    bounds_within(self.x, self.y, window)

function make(self::ColoredPoints, context::PlotContext)
    x, y = project(context.geom, self.x, self.y)
    GroupPainter(getattr(self,:style), ColoredSymbolsPainter(x, y, self.s, self.c))
end

function ColoredPoints(x::Real, y::Real, args...)
    return ColoredPoints([x], [y], args...)
end
