Plot average of range of data

Hi, I am hoping for help on the following:

I would like to take the average of the last 10 years of my data-for multiple scenarios-and then create a plot containing the combined scenarios.

I understand how to take a moving average, but am unsure how to specify solely for specific years (2060-2070).

Any help is appreciated,

Thanks!

The question is not clear. What are the inputs? Do you want a moving average or a blockwise average? Did you search in the forum already? Perhaps this helps already: https://www.mathworks.com/matlabcentral/answers/329251-average-in-a-matrix-with-different-intervals
