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

在 MATLAB Online 中打开

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

Thank you so much, it worked.
