How to plot a offset in a graph

Alright so I need to plot my graph with a 2% offset to find my yield strength. I am unsure how to go about doing this. This is what I have right now so I just need to add a 2% offset to my graph.
li=a(:,[2]).*.0392700787; % Convert mm to in
P=a(:,[3]).*224.808943; % Convert kN to lbf
Di=(2.53*.0392700787);
Ao=pi/4*Di^2;
lo=(26.11*.0392700787);
Si=P/Ao;
ei=li/lo;
plot(ei,Si)
xlabel('Strain (in/in)')
ylabel('Stress (lb/in^2)')
title('Stress vs Strain 4140 Steel')

What do you mean by a 2% offset? Translation to the right? Translation upwards?

I am not sure I understand what you want to achieve.
x = sort(rand(10,1));
y = sort(rand(10,1));
plot(x,y,'b-')
hold on
plot(1.02.*x,y,'r-')
Note that the graphs are not entirely parallel, but 2% is a relative measure and I do not see how you interpret it.
