%Plot of entire patient one time series
load ('glucose.mat')
glucose_mgdl = glucose * 18;
plot(date1+time,glucose_mgdl),
xlabel('Days'), ylabel('Glucose')
title('Glucose readings vs days/time')
M = mean(glucose_mgdl)
S = std(glucose_mgdl)
Trying to display correlogram as the picture seen below what do I have to add to my code:
%Plot of correlogram
[r,lags] = xcorr(glucose_mgdl,'coeff');
figure
plot(lags, r, '.')
grid
xlabel('Lags')
ylabel('Croorelation Coefficient')
title('Autocorrelation')

‘Trying to display correlogram as the picture seen below what do I have to add to my code:’
The plot in the documentation is a stem plot. I plotted that originally, however the data are so densely packed that it simply appears as a filled area below the curve (even when using '.' as the marker).
One option would be to select a subset of values and plot them —
%Plot of entire patient one time series
T1 = readtable('https://www.mathworks.com/matlabcentral/answers/uploaded_files/838945/glucose.csv');
glucose = T1.glucose;
date_time = T1.date + T1.time;
glucose_mgdl = glucose * 18;
plot(date_time,glucose_mgdl),
xlabel('Days'), ylabel('Glucose')
title('Glucose readings vs days/time')
M = mean(glucose_mgdl)
S = std(glucose_mgdl)
%Plot of correlogram
[r,lags] = xcorr(glucose_mgdl,'coeff');
sampstep = 10; % Sampling Step
rs = r(1:sampstep:end);
lagss = lags(1:sampstep:end);
figure
stem(lagss, rs, '.')
grid
xlabel('Lags')
ylabel('Crorelation Coefficient')
title('Autocorrelation')
Change the value of ‘sampstep’ to get different stem plot results.
