Displaying plotted real time data

I am trying to display the data that is being acquired and plotted from the microphone on real-time. It is one of the Matlab examples. How to display / save / process the data.
d = daq.getDevices;
dev = d(2);
s = daq.createSession('directsound');
addAudioInputChannel(s, dev.ID, 1:2);
%fid1 = fopen('log.bin','w');
s.IsContinuous = true;
hf = figure;
hp = plot(zeros(1000,1));
T = title('Discrete FFT Plot');
xlabel('Frequency (Hz)')
ylabel('|Y(f)|')
grid on;
plotFFT = @(src, event) helper_continuous_fft(event.Data, src.Rate, hp);
hl = addlistener(s, 'DataAvailable', plotFFT);
s.startBackground;
figure(hf);
pause(inf);
