Small and crude colorbar implementation to Winston

colorbar.jl

#colorbar
function colorbar(dmin, dmax; orientation="horizontal", colormap=_default_colormap, kvs...)

    if orientation == "vertical"
        p=FramedPlot(aspect_ratio=10.0)
        setattr(p.x, draw_ticks=false)
        setattr(p.y1, draw_ticks=false)
        setattr(p.x1, draw_ticklabels=false)
        setattr(p.y1, draw_ticklabels=false)
        setattr(p.y2, draw_ticklabels=true) 

        xr=(1,2)
        yr=(dmin,dmax)

        y=linspace(dmin, dmax, 256)*1.0
        data=[y y]
    elseif orientation == "horizontal"
        p=FramedPlot(aspect_ratio=0.1)
        setattr(p.y, draw_ticks=false)
        setattr(p.x1, draw_ticks=false)
        setattr(p.y1, draw_ticklabels=false)
        setattr(p.x1, draw_ticklabels=false)
        setattr(p.x2, draw_ticklabels=true) 

        yr=(1,2)
        xr=(dmin, dmax)

        x=linspace(dmin,dmax,256)*1.0
        data=[x', x']
    end

    setattr(p, :xrange, xr)
    setattr(p, :yrange, yr)

    setattr(p; kvs...)

    clims = (minimum(data),maximum(data))

    img = data2rgb(data, clims, colormap)
    add(p, Image(xr, yr, img))
    p
end

Thanks. I've used a version of your code here EEG.jl commit
