Trying to plot graph in a proper time series manner

*The original file is the csv file and I am trying to get a time series plot of the entire file to determine if it is stationary. Also being able to obtain a correct mean and standard deviation. However not getting a proper plot of all data.

%Plot of entire patient one time series

load ('glucose.mat')

plot(time,glucose), 
xlabel('Time'), ylabel('Glucose')
title('Glucose readings for each time of the day')

%Finding the mean of the glucose readings for the time series
M = mean(glucose)

M = 10.1941

%Finding the standard deviation of the glucose readings for the time series
S = std(glucose)

S = 4.8692

time is the time of day, so it doesn't contain information about the date, only the hours, minutes, seconds within a day. In order to plot the whole thing, you can add time to the datetime array date1 and plot glucose against the result:

%Plot of entire patient one time series

load ('glucose.mat')

plot(date1+time,glucose), 
xlabel('Time'), ylabel('Glucose')
title('Glucose readings for each time of the day')

%Finding the mean of the glucose readings for the time series
M = mean(glucose)

M = 10.1941

%Finding the standard deviation of the glucose readings for the time series
S = std(glucose)

S = 4.8692
