Here's how I sorted primarily by field 'a' descending and secondarily by field 'b' ascending:
could you multiply the numeric field by -1, sort, then put it back -- somethign like:
data *- -1 data_sorted = np.sort(data, order=['a','b']) data_sorted *= -1
(reverse if necessary -- I lost track...)

While that may work for this users case, that would not work for all dtypes. Some, such as timedelta, datetime and strings would not be able to be multiplied by a number. Would be an interesting feature to add, but I am not certain if the negative sign notation would be best. Is it possible for a named field to start with a negative sign? Ben Root
