How can I extra data from plot graph? As i have data x axis= 10,12,14,16,18 and their corresponding value on y axis= 0.6,0.9,1,0.2,1.28. Now how can I get y axis value for x axis value 20?

You can use interp1 function
x=[10,12,14,16,18]
y=[0.6,0.9,1,0.2,1.28]
xi=20
yi=interp1(x,y,xi,'linear','extrap')
