Live stream data aquisition using Myo for EMG signals

Hello I am trying to live stream data from my myo to have all 8 channels on it to stream the EMG data it collects,however the code below is just a graph of the 8 channels. How can I make this happen

%% Initializing connection to myo band

hMyo = Inputs.MyoUdp.getInstance();

hMyo.initialize();

%%

channels = 8;

time_s = 3; %This variable time is in seconds

SAMPLE_RATE = 200; %200 = hertz

num_sample = time_s * SAMPLE_RATE;

hMyo.getData(num_sample, 1:channels);

store_hMyo_data = hMyo.getData(num_sample, 1:channels);

%%

%Plot X and Y Values

figure

plot (1:num_sample, store_hMyo_data(:,1));

xlabel ('num_sample')

ylabel ('abtnum')
