If you want to superimpose a polyline on top of an existing plot
(1-d or 2-d), you can use the TGraph class.
gr = new TGraph(n, x, y)
creates a graph with the n points defined in the arrays x and y.
To draw the graph
Root > gr->Draw("L")
You could also use the TPolyLine class, but the TGraph class
has more drawing opotions and it also works for log scales.
