Add an option to change the Area Charts fill color. Currently it's a slightly brighter version of the line color, but people might want to change it. (I did, wanted a brighter color there).
fillForSeries: (i) ->
fill_color = @options.fillAreaColors[i]
return fill_color if fill_color
color = Raphael.rgb2hsl @colorFor(@data[i], i, 'line')
Raphael.hsl(
color.h,
Math.min(255, color.s * 0.75),
Math.min(255, color.l * 1.25))
