Real time plot for multiple channels qith National Instruments

Hi, I apologize in advance for my bad english, hope you understand. I am currently attempting to acquire two signals from a NI USB6009 in order to plot both of them in real time, but I can't manage to plot the channel 'ai1', actually, it plots the same graphic of the 'ai0'. The code that I already have is this:

clc
clear all
s = daq.createSession('ni');
addAnalogInputChannel(s,'Dev1', 0:1, 'Voltage');
s.Rate = 1000;

 tc1 = s.Channels(1);
set(tc1);
tc1.Range = [-5 5];
tc1.TerminalConfig = 'SingleEnded';

 tc2 = s.Channels(2);
set(tc2);
tc2.Range = [-5 5];
tc2.TerminalConfig = 'SingleEnded';

 s.DurationInSeconds = 3;
figure
subplot(2,1,1)
h1=animatedline;

 ylim([0 6])
grid on
lh1 = addlistener(s,'DataAvailable', @(src,event) addpoints(h1,event.TimeStamps(1), event.Data(1)));
drawnow
s.NotifyWhenDataAvailableExceeds = 100;
s.startBackground();
hold on
subplot(2,1,2)
h2=animatedline;
xlim([0 30])
ylim([0 6])
lh2 = addlistener(s,'DataAvailable', @(src,event) addpoints(h2,event.TimeStamps(2), event.Data(2)));
drawnow
s.wait()
