Multiple animated lines in two different figures plotted simultaneously

Hello,
I am currently using a self built 3D-printed pressure sensor to get realtime reading in terms of change in the capacitance. The sensor has two different sensing areas. I currently have a code which displays the pressure from those two sensing areas, as shown in the figure below.
I would like to have another figure along with this, which display load values from the same sensor simultaneously. So, two figures, one as the same figure below and another figure with converted load values displayed simultaneously. Instead of two figures, a subplot would also work I suppose. The entire code is in a while loop. I tried the following:
figure(1)
h = animatedline('Color','r','LineWidth',1);
h2 = animatedline('Color','b','LineWidth',1);
figure(2)
h3 = animatedline('Color','g','LineWidth',1);
h4 = animatedline('Color','m','LineWidth',1);
ax = gca;
ax.YGrid = 'on';
ax.YLim = [-200 400];
legend('1','2')
while ~stop
% After reading the input from the sensor
addpoints(h,datenum(t),senleft)
addpoints(h2,datenum(t),senright)
addpoints(h3,datenum(t),strru1)
addpoints(h4,datenum(t),strrd1)
end
Thank you in advance. Please let me know if you need any further information.

Subplot is easy to use:

I see.
datetick can take axis_handle as the first input paramter.
clear all
close all
s=serialport('COM7',9600);
configureTerminator(s,"CR/LF")
sub1=subplot(2,1,1);
h = animatedline('Color','r','LineWidth',1);
h2 = animatedline('Color','b','LineWidth',1);
ax1 = gca; % NEED TO DISTINGUISH UPPER SUBPLOT AND LOWER ONE
ax1.YLim = [0 400];
legend('1','2')
subplot(2,1,2)
h3 = animatedline('Color','r','LineWidth',1);
h4 = animatedline('Color','b','LineWidth',1);
ax2 = gca; % NEED TO DISTINGUISH UPPER SUBPLOT AND LOWER ONE
ax2.YLim = [-1000 2000];
legend('3','4')
startTime = datetime('now');
while ~stop
str = readline(s);
t = datetime('now') - startTime;
% Add points to animation
addpoints(h,datenum(t),senleft)
addpoints(h2,datenum(t),senright)
addpoints(h3,datenum(t),strlu)
addpoints(h4,datenum(t),strld)
i=i+1;
% Update axes
ax1.XLim = datenum([t-seconds(15) t]); % UPDATE UPPER. Is this what you want?
ax2.XLim = datenum([t-seconds(15) t]); % UPDATE LOWER
datetick(ax1, 'x','keeplimits') % UPPER
datetick(ax2, 'x','keeplimits') % LOWER
drawnow
end
