Display only timeseries years

Hi,

I have time-series data from 1958 to 2019.

The smallest unit of time is 1 hour (from 2014 to 2019)

The smallest unit of time is 3 hours (from 1958 to 2013)

The y-variable is temperature

The data looks like this

What code should I use to display the temperature data in yearly intervals on a figure?

(I assume I must take the average temperatures across the years) - how?

Thank you.

Based on the image you shared, your data are arranged in a table, not a timetable. Using a timetable will be useful so you can easily convert your data to a timetable using

TT = table2timetable(T)

Then you could compute the annual means by following this exmple in retime() except you'll use yearly time steps instead of hourly.

If you have any problems implementing this, show us your code and we can help straighten it out.
