Convert datetime to time of day, to be able to plot along time (e.g. 08:00, 10:00, 12:00 14:00...)

Hello,

I have data in this format:

• I want to convert the datetime into the time only (in HH:mm) to be able to plot the temperature along the time of the day.

My goal is to produce this graph, but just for one whole day:

Read abput datevec. From here you should be able to pick your time.

Read about it, but I dont think its helpful.

I found this timeofday function:

dur = timeofday(Time)

It gives me exactly the output that I need. However it's class is 'duration', and can not be plotted along the X-axis. Is there a way to change the class to a 'normal' vector which can be plotted?

YOu have to plot w.r.t indices and then label the axes using xtick

The ability to use datatime or duration objects for the axes is new in R2016b. Which MATLAB version are you using?

Answer 1

[Neil Guertin]

Use the timeofday function to convert your datetime objects to duration objects. You should be able to use the duration objects on the x axis just as you would use datetime objects. If you are not able to, please post the error message you are seeing.
