The built=in function *ListPlot* should do what you are looking for. You 
have to generate a list of pairs (I use *Table* in the example below to 
do so) either before calling *ListPlot* or directly inside it. For instance,

ListPlot[Table[{v1[100], D1[100]/v1[100]} /.
    L94[0.04, 0.20, 0.06, 0.5, 0.35, c], {c, 0, 15}]]

HTH.
