Legend for plot genereted by a loop

I want to plot 2 variables and each row of the 2 variables to be presented with different color. So I wrote the following code which plot through loop:
plot(Xindex2plot,Yindex2plot,'color',cc(allSS,:));
However, I have problem with the legend. At legend it is presented only the color of the last row of data and the text respectively. This is the code for the lgend which it is supposed that produced through loop also.
% s{allSS}=sprintf('%s',nameofsource2open);
% legend(plotall,s)
How I should reform it to present all the data and the texts?
Thank you in advnace

Store a handle to each plot in h(i) and let the legend refer to this handle h:
col = rand(3, 3);
data = rand(3, 100);
axis, hold on, for i=1:3, h(i) = plot(data(i,:), 'Color', col(i,:)); end
legend(h, {'data1' 'data2' 'data3'})

Thank you for your help!!!
If I dond't know the text for the legend because it will be defined by a variable that changes. How I should define to read the text of a variable and use it as text for legend?
Thank you again!!!
In the loop:
legendtext{i} = variable_that_changes;
and then
legend(h, legendtext)
Thank you very much!!!
It works!!! Thank you very much
