MATLAB: How is datevec used on an m*8 matrix in the form [YEAR, MONTH, DAY, HOUR, MINUTE, SECOND, Day of Year, Value]

I have an m*8 array with the form [YEAR, MONTH, DAY, HOUR, MINUTE, SECOND, Day of Year, Value], and I am unsure how to use datevec or another appropriate function to make the array easier to use, by graphing years, months and days etc. How can I do this?
