Maybe there is a more compact way, but Theme(default_color=color(<color>)) in layer and Guide.manual_color_key in plot should work, for example:
x0= [1:10] y1 = rand(10) y2=rand(10) l1 = layer(x= x0, y = y1, Geom.line, Theme(default_color=color("red"))) l2 = layer(x= x0, y = y2, Geom.line, Theme(default_color=color("green"))) plot(l1, l2, Guide.manual_color_key("hello",["line1","line2"], ["red", "green"])) sebastian On Monday, July 6, 2015 at 7:33:35 AM UTC-5, m wrote: > > Hello, > > I am using Gadfly packages to perform graphs as: > > plot(layer(x=A,y=sum(PWN_vec,1),Geom.line, > Theme(default_color=color("orange"))), > > > layer(x=A,y=sum(PCN_vec,1),Geom.line,Theme(default_color=color("purple"))),Guide.xlabel("Wind > > uncertainty"), Guide.ylabel("Total capacity to be installed")) > > > But I cannot include a legend indicating one color for each layer, someone > could help me? > > thank you in advance > > kind regards >
