Im trying to plot the following using layers...though do I have to load it separately or why doesnt it work?
julia> plotcomb=plot( layer( x=Q_l, y=cal_corr ), layer( x=Q_l, y=cal_corr, Geom.line ), Theme(panel_opacity=0.1) ) Error showing value of type Gadfly.Plot: ERROR: MethodError: `render` has no method matching render(::Gadfly.Geom.Nil, ::Gadfly.Theme, ::Gadfly.Aesthetics) Closest candidates are: render(::Gadfly.Geom.Nil, ::Gadfly.Theme, ::Gadfly.Aesthetics, ::Gadfly.Data, ::Dict{Symbol,Gadfly.ScaleElement}, ::Array{Gadfly.Aesthetics,1}) render(::Gadfly.GeometryElement, ::Gadfly.Theme, ::Gadfly.Aesthetics, ::Union{Array{Gadfly.Aesthetics,1},Void}, ::Union{Array{Gadfly.Data,1},Void}, ::Dict{Symbol,Gadfly.ScaleElement}) render(::Gadfly.Geom.BarGeometry, ::Gadfly.Theme, ::Gadfly.Aesthetics) ... in render at C:\cygwin64\home\Diger\.julia\v0.4\Gadfly\src\geometry.jl:47 in render_prepared at C:\cygwin64\home\Diger\.julia\v0.4\Gadfly\src\Gadfly.jl:782 in render at C:\cygwin64\home\Diger\.julia\v0.4\Gadfly\src\Gadfly.jl:721 in display at C:\cygwin64\home\Diger\.julia\v0.4\Gadfly\src\Gadfly.jl:973 [inlined code] from multimedia.jl:151 in display at C:\cygwin64\home\Diger\.julia\v0.4\Gadfly\src\Gadfly.jl:151 in print_response at REPL.jl:134 in print_response at REPL.jl:121 in anonymous at REPL.jl:624 in run_interface at LineEdit.jl:1610 in run_frontend at REPL.jl:863 in run_repl at REPL.jl:167 in _start at client.jl:453
