BoxWhiskerChart and a Vertical Line on same graph

Here is a BoxWhisker graph, which is only a slight variation on one of the examples for BoxWhisker graphs in the documentation. data=Table[RandomVariate[NormalDistribution[RandomInteger[5],1],100],{2},{2}]; grBox1 = BoxWhiskerChart[data, ChartLegends->{"a","b"},AxesLabel->{"Quintile", "Price"}, Frame->False, Axes->True, AxesOrigin->{0,0} ] I would like to superimpose a vertical line on the graph between the first and second PAIR of boxes (i.e. between the first two and the second two). My attempt to do this is the following: xv = 10; graphicLine = Graphics[Line[{{xv,0},{xv,8}}]] ; Show[grBox1,graphicLine] but this produces no graph and an error message in the pink window which says: "Labeled is not a Graphics primitive or directive" But, I am not using anything in the code above which is called "Labeled". Is there a way to superimpose this line on the BoxWhisker Chart? Thank you in advance. Don
