How could I use Legend function in a for loop with an array?

Hi! everyone I am trying to insert a Legend in a plot with different names but in a sequence. The problem basically is when I plot Legend, it only show me the first or the last filename I require. So I hope you can help me because I tried with different methodologies and it doesn't work. My code is the next:
for k=1:numfiles
figure(2)
legend(filename(k));
plot3(f{1,k}'/1000,((k*10^2)*10^6)+Ejey{1,k},2*q_magC{1,k},(colour(k)))
title('TRANSFORMADA DE FOURIER')
xlabel(' Frecuencia (kHz) ')
zlabel(' Magnitud ')
view(40,35)
grid on
hold all
end
Thanks in advance!

Jose - if I do something similar and create the legend outside of the loop (or even as you have shown above within at each iteration of the loop), then all of the filenames appear as expected as legend entries. Can you show us what the filename variable is initialized to? How many curves are being drawn on your figure?

%try like this
s = {'L1','L2','L3'};
for i = 1:length(s)
plot(rand(10,1),'color',rand(1,3));
hold on
end
legend(s)
