Since you can set the stroke color and such for the lineSeries, then simply make your own container with the check Boxes, label and images representing the legend. You don't need to use a legend itself.
my problemb is how to get that shape and use in container .
i am using hbox in that i have checkbox ,label and i tried to use Image or IFlexDisplayObject but i am unable to assign that renderer to either image or IFlexDisplayOBject nothing isd working.
any suggestion for what component i shall use to assign the itemrenderer of lineseries.
Thanks for replying
