Hi Travis, Very Strange. I am on version 1.6.2 L What could I be missing. I started using numpy quite recently. Is there a way to share the data with you? Regards, Alok Jadhav GAT IT Hong Kong +852 2101 6274 (*852 6274) From: numpy-discussion-bounces@scipy.org [mailto:numpy-discussion-bounces@scipy.org] On Behalf Of Travis Oliphant Sent: Tuesday, September 11, 2012 11:58 AM To: Discussion of Numerical Python Subject: Re: [Numpy-discussion] numpy sort is not working Hey Alok, This is worth taking a look. What version of NumPy are you using? It is not related directly to the issue you referenced as that was an endian-ness issue and your data is native-order. Your example seems to work for me (with a simulated case on 1.6.1) Best, -Travis On Sep 10, 2012, at 10:46 PM, Jadhav, Alok wrote: Hi everyone, I have a numpy array of dimensions
allRics.shape (583760, 1)
To sort the array, I set the dtype of the array as follows: allRics.dtype = [('idx', np.float), ('opened', np.float), ('time', np.float),('trdp1',np.float),('trdp0',np.float),('dt',np.float),('value' ,np.float)]
allRics.dtype
dtype([('idx', ' x=np.sort(allRics,order='time') x[17330:17350]['time'] array([[ 61184.4 ],

Time column doesn't change its order. Could someone please advise what
is missing here? Is this related to the bug
