Insert legend in a for loop

I'm producing a figure inside a for loop and would like to insert a legend. The script for the figure is as follows:

Name={'Data1','Data2','Data3'};
cmap = hsv(length(fieldnames(Data)));
str = 'LWST : '; 
for i=1:length(fieldnames(Data));
     plot(Data.(Name{i}),'Color',cmap(i,:));hold on         
end

So, in order to insert a legend I include the following command in the loop:

legend(Name(i));

But the legend just overlies the previous one. So, instead of having a legend showing the 3 datasets it only shows one! what should I do?

Move your legend command outside the loop ...

for i=1:length(fieldnames(Data));
   plot(Data.(Name{i}),'Color',cmap(i,:));hold on         
end
legend(Name);
