Legend in a "for loop"

hi,

I need to insert a legend for each ii evalueted.

giri can change in size at every simulation.

for ii=1:length(giri)
figure(3);
plot(m(indice_m_0:loc(ii)),psic_pos(ii,indice_m_0:loc(ii)));
grid on
hold on
end

Try :

for ii=1:length(giri)
figure(3);
plot(m(indice_m_0:loc(ii)),psic_pos(ii,indice_m_0:loc(ii)),'DisplayName',['ii = ',num2str(ii)]);
grid on
hold on
end
legend show

so and so.

It displays the index not the value of the ii element.

I would like to display N=values

figure(3);
for ii=1:length(giri)
    plot(m(indice_m_0:loc(ii)),psic_pos(ii,indice_m_0:loc(ii)),'DisplayName',['giri = ',giri(ii)]);
    grid on
    hold on
end
legend show

[Paul Rogers]

yes, but I don't know why, instead of the ii-value it shows chines letters.

I attached the file.

[Walter Roberson]

figure(3);
for ii=1:length(giri)
    plot(m(indice_m_0:loc(ii)),psic_pos(ii,indice_m_0:loc(ii)),'DisplayName',sprintf('giri = %g',giri(ii)));
    grid on
    hold on
end
legend show

Change the %g format to whatever you need.

probably because of an implicit conversion from double to char

maybe this would work:

plot(m(indice_m_0:loc(ii)),psic_pos(ii,indice_m_0:loc(ii)),'DisplayName',['giri = ', num2str(giri(ii))]);

next time it would be better if you attach the data, without sample data helping you is pretty much guesswork...
