Many legend on a figure

Hello ,

I would like to put 3 legend and 3 curves on the same figure, I tried this:

figure(1)%
plot(t,I(:,2),'b','linewidth',1.5);grid on
legend('ids');
xlabel('time[sec]');
ylabel('Courant ids');

hold on
plot(t,I(:,3),'r','linewidth',1.5);grid on
legend('iqs');
xlabel('time[sec]');
ylabel('Courant iqs');

hold on
plot(t,I(:,4),'g','linewidth',1.5);grid on
legend('if');
xlabel('time[sec]');
ylabel('Courant if');

but it does not work.

Do you have a solution ?

Why do you want separate legends though? You can have one legend statement at the end with all 3 linestyles described

for example, in the preceding example, I want to display id (blue line), iq (red line) and if (green line)

like iqk, i also want ids, iqs, if ...

Why should anyone answer this question when it is almost certain that you will attempt to get rid of the question afterwards?

Okay
