Plot stress strain curve

Hi, I need to plot a stress strain curve.
Load: I have saved in my workspace as a row vector (160x1)
extresion: I have saved in my workspace as a row vector (160x1)
When I run the code below, I do get a graph, but however it is not a stress strain graph. A friend told me I need do something like a for loop?... Im not fully sure how to go about that, can anyone help please.
force = load;
area = 847.936;
stress = force/area;
strain = (69.69-extension)/69.69;
plot(strain, stress)
xlabel('strain')
ylabel('stress')

  • Hi, I need to plot a stress strain curve.
Did you try plot()?

Your code appears to be correct. What does the plot look like, and what do you believe the plot should look like?
This is the graph I get.
O.K.
What sort of plot were you expecting?
It's okay. I figured it out. Thanks.
@Micheá McDonagh How did you end up doing it?
