Re: plot legend with filling


ListPlot[{v1, v2},
    Frame -> True,
    Axes -> False,
    Filling -> Axis,
    PlotStyle -> {
        {AbsolutePointSize[6], Red},
        {AbsolutePointSize[6], Blue}},
    FillingStyle -> {
        1 -> Directive[AbsoluteThickness[4], Blue],
        2 -> Directive[AbsoluteThickness[4], Red]},
    PlotLegend -> {"v1", "v2"},
    LegendPosition -> {-0.75, 0.25},
    LegendSize -> 0.3,
    LegendShadow -> None]
