Re: assigning array indexes using gsn_csm_hov

Gina,

Try making a second array variable that is a reordered subset of
pacav. Use vector subscripting to get the subset and the order you
want. Something like this (untested):

    months = (/ 10, 11, 0, 1, 2, 3 /) ; November to April
    rotated = pacav( months , : )
    plot = gsn_csm_hov (wks, rotated, res)

This should also carry over the correct reordered coordinates and
attributes. HTH.

Vector subscripting is documented here:

"There is more than one way to do this." ;-)
