What should I change in this code for me to get in the command window a 10 data of acceleration with 1 data for 1 second?

a = arduino();
imu = mpu6050(a,'SampleRate',50,'SamplesPerRead',10,'ReadMode','Latest');
figure;
xlabel('Time (s)');
ylabel('Acceleration (m/s^2)');
title('Acceleration values from mpu6050');
x_val = animatedline('Color','r');
y_val = animatedline('Color','g');
z_val = animatedline('Color','b');
stop_time = 10; % time in seconds
count = 1;
tic;
while(toc < stop_time)
data = read(imu);
addpoints(x_val,count:(count+imu.SamplesPerRead-1),data.Acceleration(:,1));
addpoints(y_val,count:(count+imu.SamplesPerRead-1),data.Acceleration(:,2));
addpoints(z_val,count:(count+imu.SamplesPerRead-1),data.Acceleration(:,3));
count = count + imu.SamplesPerRead;
pause(0.001);
end
release(imu);

The code plots the first row out of each group. The groups are taken at 10 Hz and 10 are read at one time, so one second of data is read at a time, but you do not bother to plot the data corresponding to .1,.2,.3,.4,.5,.6,.7,.8,.9 of the second, just the .0 of each second.
