How can I make an 2 simultaneous animated line plots?

Thanks to Cris in my previous question here, one animated plot has been successful!

1) I wonder if it is possible to do 2 simultaneous plots from the same table as tiles?

I tried it here, but I seem to have an error message, even after I remove all the appearances settings:

%set(groot,'defaultfigureposition',[0 0 1000 1000])
a1 = animatedline;%('color',[1 1 1]);
axis([0 3 0 1650])
a2 = animatedline;%('color',[1 1 1]); % NEW ADD IN
axis([0 3 0 1650]) % NEW ADD IN

%appearances settings
%title('POL AF7 EEG', 'color',[.5 .5 .5])
%xlabel('Time (s)')
%ylabel('Voltage (uV)')
%set(gcf,'color',[0 0 0])
%set(gca,'color',[0 0 0])
%set(gca,'xcolor',[.5 .5 .5])
%set(gca,'ycolor',[.5 .5 .5]) 


opts = detectImportOptions("d_museMonitor_2021-01-21--18-36-17.csv");
opts.VariableNamesLine = 1;
T = readtable('d_museMonitor_2021-01-21--18-36-17.csv',opts);
fs=256;
t = ((1:height(T))-1)/fs;

v = VideoWriter('2_channel.mp4','MPEG-4');
open(v);

for k = 1:height(T)    
    
    tiledlayout(2,1) % NEW ADD IN

    
    nexttile % NEW ADD IN
    addpoints(a1, t(k), T.RAW_AF7(k)) % ERROR LINE
    title('AF7') % NEW ADD IN
    
    nexttile % NEW ADD IN
    addpoints(a2, t(k), T.RAW_AF8(k))
    title('AF8') % NEW ADD IN
    
    frame = getframe(gcf);
    writeVideo(v,frame);
    
    % set the xlims to create a scrolling window
    xlim([max(0, t(k)-3) max(3, t(k))])
    drawnow limitrate
    

end

close(v);

This is the error message:

Error using matlab.graphics.animation.AnimatedLine/addpoints
Value must be a handle.

Error in 2_channel (line 33)
    addpoints(a1, t(k), T.RAW_AF7(k))

The image I get I will also attach here.

Thanks in advance for your kindest assistance!

Real neat and complex animation! Though the code was pretty complex, yet it gave me some ideas as to what might have been the problem.Thank you @KSSV.

Haha, I found this similar question afterwards and edited the code to suit my needs. Welcome anyone who has any more suggestions!

clear all
clc
set(groot,'defaultfigureposition',[0 0 1000 1000]);
opts = detectImportOptions("d_museMonitor_2021-01-21--18-36-17.csv");
opts.VariableNamesLine = 1;
T = readtable('d_museMonitor_2021-01-21--18-36-17.csv',opts);
fs=256;
t = ((1:height(T))-1)/fs;
y1 = T.RAW_AF7;
y2 = T.RAW_AF8;
ymax = max(max(y1, y2));
