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?

1980 1 1 2 0 0 1 -23

1980 1 1 3 0 0 1 -28

1980 1 1 4 0 0 1 -32

1980 1 1 5 0 0 1 -32

1980 1 1 6 0 0 1 -32

data = [1980  1  1  0  0  0  1  -27

1980  1  1  1  0  0  1  -20

1980  1  1  2  0  0  1  -23

1980  1  1  3  0  0  1  -28

1980  1  1  4  0  0  1  -32

1980  1  1  5  0  0  1  -32

1980  1  1  6  0  0  1  -32

1980  1  1  7  0  0  1  -31

1980  1  1  8  0  0  1  -33];

d = data(:,1:end-2) ;
val = data(:,end) ;
date = datetime(d) ;
plot(date,val)

datetime() doesn't work on R2008b, any suggestions for an older version?
