Assuming the y-axis is different for the scatter line segment plot, you probably want to use twoord.plot() in package plotrix to construct overlapping plots using different ordinate (y-axis) scales. For examples see

I can make two density plot together(I have attached that plot), but together with these density plot, I cannot include scatter line-segment plot on this density plot.
