At present, ListPlot will not show points and lines together Here is one
way round - you could build this into a function ListPlotPL with two
extra options LineStyle and PointStyle.

    {PlotJoined -> True,PlotStyle->{Thickness[.01],Hue[2/3]}
     {PlotStyle->{PointSize[0.05], Hue[0]}}


The following might help
