Hello, this should correct your problem. Where the comments are, is where i have made changes. The rest of your code remains the same
t1 = datetime(2016,5,4,13,45,0);
t2 = datetime(2016,5,4,14,15,0);
t = t1:minutes(1):t2;
t = t';
[h,m] = hms(t);
for i = 1:length(t)
if m(i) == 0 || 1 || 2 || 3 || 4 || 5 || 6 || 7 || 8 || 9
% specify the minimum width on both the hour and minute side as "2" but with a leading zero on the minute side
time_axis{i} = sprintf('%2d:%02d',h(i),m(i));
else
% specify the minimum width on both the hour and minute side as "2", but with a leading zero on the minute side
time_axis{i} = sprintf('%2d:%02d',h(i),m(i));
end
end
clear i;
time_axis = time_axis';
