Hey, so I got a variable of duration that has de time of each message that goes from 00:00:00 to 23:59:59 and I want to make a plot that show me the amount of messages each hour. How could I do it? I made this but I got an error:
Hours_24 = (0:1:23)/24;
figure(1)
plot(Hours_24,Time_AIS1);
The error showed is:
Error using plot
Vectors must be the same length.

well I've got Time_AIS1 that has the time of all the messages and I want a figure that shows me 24 columns where each column has the mesages that have the same Hour. In total there should be just 24 columns.

Easy solution might be this, e.g.:
N = numel(Time_AIS1);
figure(1)
stem(1:N, Time_AIS1), xlabel('Hour'), ylabel('# of messages')
