The problem I have here is that using the default add marker in the code or the Fig editor, doesn't really work since I have tons of data points. Is there anyway to set markers on specific intervals so they do not over lap? Below is the code I am using for three figures:

figure(Fig_true);

plot(true_strain(1:a,1),true_stress(1:a,1),'b','linewidth',3);

figure(Fig_eng);

plot(eng_strain,eng_stress,'b','linewidth',3);

figure(Fig_strain_h);

plot(true_strain(1:a,1), strain_h,'b');

:D, those are just names of the figures, I named them so when I run the code they don't get confused with each other. With marker, I just mean plain markers on the curves, like circle or cross or whatever. As I understand matlab puts a marker on each of the data points, since I have 1000+ points it messes up the curve.

I knew that, but why did my code suggestion below not meet your needs?

Sure. You can try

% Plot elements 1-100 in blue dots
plot(true_strain(1:100,1),true_stress(1:100,1),'b.');
hold on;
% Plot elements 101-200 in red crosses
plot(true_strain(101:200,1),true_stress(101:200,1),'r+');
% Plot elements 201:300 in green squares
plot(true_strain(201:300,1),true_stress(201:300,1),'gs');
