Plot of a Time Variable

Hi,

so I have a variable that has the time of arrival of different messages from 00:00:00 to 23:59:59. What I want is to get a figure of bars where each bar has the messages from an Hour. There would be a total of 24 bars.

How could I do it?

Hi Vicente,

Are you looking for this?

>> bar(duration([1 2 3],0,0),[5 1 10])

Thanks,

Lei

Hi yeah I was meant to do that

[flashpode]

could you explain why if I put:

bar(Time_AIS1)

I do not get the same figure, I mean my variable is already a duration

As you have data every second, you need to do hourly mean to get 24 values. You have two options.

1. Reshape the data into 24*m; use mean and then plot the data.
2. USe retime to get hourly average and then plot.

I have a variable of duration and retime gives me a timetable
