I want to combine all plots in same axes, I tried to use hold on and hold off but it didn't work. Can anybody help me? Here's a part of the code:
for i=1:it
if i<=3
figure('Color','w');
hold on; box on; grid on;
params.flag_plot = 0;
npts = 41;
ec_max_vec = ec_max + linspace(0,abs(ec_max),npts);
Mtotal = zeros(npts,1);
Ntotal = zeros(npts,1);
for pt=1:npts
ec_max = ec_max_vec(pt);
x = fminbnd(@(x) EquilibriumVerification(x,ec_max,params,d,fy,Es,ey,Ast,b,h,ft,Ec,ec0,k3,fc,ecu),0,h,options);
[Fs,Fcc,Fct,Mc,Ms] = ComputeForcesAndMoments(ec_max_vec(pt),x,params,d,fy,Es,ey,Ast,b,h,ft,Ec,ec0,k3,fc,ecu);
Mtotal(pt) = Mc + Ms;
if (sign(Mc)~=sign(Ms))
disp('Here')
pause
end
Ntotal(pt) = Fs + Fcc + Fct;
end
plot(abs(ec_max_vec),abs(Mtotal)/100,'-b','DisplayName','Bending Moment (kN.m)')
plot(abs(ec_max_vec),Ntotal,'--r','DisplayName','Error (kN)')
l1 = legend;
set(l1,'Location','Southeast')
xlim([0 abs(ec_max_vec(1))])
xlabel('\epsilon_c_m_a_x','FontName',params.font_name,'FontAngle','italic','FontSize',params.font_size)
end
end

xlim([0 abs(ec_max_vec(1))])
You will need to track the maximum abs() over all of the plots and xlim with that after the loops
Also you should probably
ylim auto
after all the loops
