What I ended up doing was getting my array to look like: from numpy import nan aa = [3.4,2.5,nan,nan,nan,1.1,2.2] values = numpy.array(aa) values = numpy.ma.masked_equal(values,nan) I only wish that masked_equal didn't blow up when aa contains datetime objects :-( cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
