Question: how to plot a graph with 3 coordinates in 2D


i have 3 Arrays and i want to plot them i 2D, 

for example : 

y  := [1,2,3,4,5,6]

x1:= [10,20,30,40,50,60] 

x2:= [0.1,0.2,0.3,0.4,0.5,0.6]

and i want to display at the graph for each y point the value of x1 and x2 by two axis (dualaxis)

any suggestions ?
