How can I get a plot legend to give a different value for every input file?

I have a code that plots some data:

D = 'My Directory';
S = dir(fullfile(D,'LIV Data T= *.mat'));  %   Makes a structure with all files
N = numel(S);   %   Counts number of files
for ii = 1:N
    T = load(fullfile(D,S(ii).name));   % Load each file as a structure
    I = T.num(3:end,1);                 % Extract each parameter from full file and ignore first two data points
    V = T.num(3:end,2);
    P = T.num(3:end,3);
    figure(1);
    plot(I,P,'-o','markers',3)
    xlabel('Current (mA)')
    ylabel('Power (mW)')
    hold on
    figure(2);
    plot(I,V,'-o','markers',3)
    xlabel('Current (mA)')
    ylabel('Voltage (V)')
    hold on
end

I am trying to create a plot legend for each data file saying T=10 for the first, T=15 for the second, etc. such that the plot has a full legend shown for each line. How do I go about this?
