error on drawing a horizontal line

[yordiak]

hello,

i am using Gadfly (v1.3) and julia (v1.4.2) on a wn10 64bit machine

the code

f(x)=x/(1-x)
plot(f,0,0.8, yintercept=1.5,  Geom.hline(style=:dot))

produces an error

Couldn't process recipe args: (typeof(f), Int64, Float64, Gadfly.Geom.HLineGeometry)

what am I missing?

Gadfly mainly expects vectors for aesthetics (unless your referring to a column in a Dataframe), even one-length vectors. This works for me:

using Gadfly
f(x)=x/(1-x)
p = plot(f,0,0.8, yintercept=[1.5],  Geom.hline(style=:dot))

Also see #1430 which lists the current syntaxes available for the color aesthetic.
