PAPR of multiple subcarriers on the same graph

Hello i am currently working on PAPR in OFDM using matlab.How do i modify the code below so that i can display PAPR for totalSubcarriersd,256,512,1024 on the same graph?This code only display totalSubcarriersd.

function paprOFDMA()

dataType = 'Q-PSK'; % Modulation format.
totalSubcarriers = 64; % Number of total subcarriers.
numSymbols = 16; % Data block size.
Fs = 5e6; % System bandwidth.
Ts = 1/Fs; % System sampling rate.
Nos = 4; % Oversampling factor.
Nsub = totalSubcarriers;
Fsub = [0:Nsub-1]*Fs/Nsub; % Subcarrier spacing
numRuns = 1000; % Number of runs.

papr = zeros(1,numRuns); % Initialize the PAPR results.

for n = 1:numRuns,
% Generate random data.
if dataType == 'Q-PSK'
tmp = round(rand(numSymbols,2));
tmp = tmp*2 - 1;
data = (tmp(:,1) + j*tmp(:,2))/sqrt(2);
elseif dataType == '16QAM'
dataSet = [-3+3i -1+3i 1+3i 3+3i ...
-3+i -1+i 1+i 3+i ...
-3-i -1-i 1-i 3-i ...
-3-3i -1-3i 1-3i 3-3i];
dataSet = dataSet / sqrt(mean(abs(dataSet).^2));
tmp = ceil(rand(numSymbols,1)*16);
for k = 1:numSymbols,
if tmp(k) == 0
tmp(k) = 1;
end
data(k) = dataSet(tmp(k));
end
data = data.';
end

% Time range of the OFDM symbol.
t = [0:Ts/Nos:Nsub*Ts];

% OFDM modulation.
y = 0;
for k = 1:numSymbols,
y= y + data(k)*exp(j*2*pi*Fsub(k)*t);

end

% Calculate PAPR.
papr(n) = 10*log10(max(abs(y).^2) / mean(abs(y).^2));
end

%Plot CCDF.
[N,X] = hist(papr, 100);
semilogy(X,1-cumsum(N)/max(cumsum(N)),'b')
xlabel('papr, x dB')
ylabel('ccdf')
