Hello everyone,
I have a little problem here, i plot 8 different curves on a figure but i want to hide the legend for the four last of them since they are only the new step of my simulation, does anybody has an idea to keep the legend for the first of them but hide it for the 4 last ones
TimeStead=max(TimeMeasurStead,TimeRealStead);
TimeStead=max(TimeStead,TimeVelStead);
xx1 = linspace(0,TimeStead(1),1e3).';
xx2 = linspace(0,TimeStead(2),1e3).';
xx3 = linspace(0,TimeStead(3),1e3).';
xx4 = linspace(0,TimeStead(4),1e3).';
tt1 = linspace(TimeStead(1),2000,1e3).';
tt2 = linspace(TimeStead(2),2000,1e3).';
tt3 = linspace(TimeStead(3),2000,1e3).';
tt4 = linspace(TimeStead(4),2000,1e3).';
tstead1=find(Tout1>TimeStead(1));
tstead2=find(Tout2>TimeStead(2));
tstead3=find(Tout3>TimeStead(3));
tstead4=find(Tout4>TimeStead(4));
M=[0,0,0,0];
IC2=[Xout1(tstead1(1),1);Xout1(tstead1(1),2);Xout1(tstead1(1),3);Xout1(tstead1(1),4)];
IC3=[Xout2(tstead2(1),1);Xout2(tstead2(1),2);Xout2(tstead2(1),3);Xout2(tstead2(1),4)];
IC4=[Xout3(tstead3(1),1);Xout3(tstead3(1),2);Xout3(tstead2(1),3);Xout3(tstead2(1),4)];
IC5=[Xout4(tstead4(1),1);Xout4(tstead4(1),2);Xout4(tstead4(1),3);Xout4(tstead4(1),4)];
opts= odeset('RelTol',1e-8,'AbsTol',1e-10);
[~,Xout11] = ode45(@(t,x)mydyn(t,x,M(1)),tt1,IC2,opts);
[~,Xout21] = ode45(@(t,x)mydyn(t,x,M(2)),tt2,IC3,opts);
[~,Xout31] = ode45(@(t,x)mydyn(t,x,M(3)),tt3,IC4,opts);
[~,Xout41] = ode45(@(t,x)mydyn(t,x,M(4)),tt4,IC5,opts);
%data visualisation
figure(8);
plot(tt1,Xout11(:,1),'b','linewidth',2,'displayName','M= 5 Nm');
xlabel('$t$(s)','interpreter','Latex')
ylabel('$T$(K)','interpreter','Latex')
set(gca,'FontSize',11)
hold on;
plot(tt2,Xout21(:,1),'g','linewidth',2,'displayName','M= 15 Nm');
plot(tt3,Xout31(:,1),'r','linewidth',2,'displayName','M= 25 Nm');
plot(tt4,Xout41(:,1),'k','linewidth',2,'displayName','M= 55 Nm');
plot(xx1,Xout1(:,1),'b','linewidth',2,'displayName','');
plot(xx2,Xout2(:,1),'g','linewidth',2,'displayName','');
plot(xx3,Xout3(:,1),'r','linewidth',2,'displayName','');
plot(xx4,Xout4(:,1),'k','linewidth',2,'displayName','');
lgd=legend;
[TimeSteadFinal,TempSteadFinal]=ginput(4);
TimeSteadFinal=TimeSteadFinal-TimeStead;
hold off;

If you aren't fussed about actually doing this within the code then you can select the lines, open up the property editor, find the property called "Handle Visibility" and set this to "Off".
If you want to do this in your code then you can insert 'HandleVisibility','off' instead of 'displayName','' in the plotting commands of those lines you don't want labelled.
I think that should work! If not then comment back on here and let me know.
