[Numpy-discussion] unclear output format for numpy.argmax()

Hello, There are some doubts that i have regarding the argmax() method of numpy.As described in reference doc's of numpy,argmax(axis=None,out=None) returns the indices of the maximum value along the given axis(In this case 0 is default). So, i tried to implement the method to a 2d array with elements say,[[1,2,3],[4,5,6]] along the axis 1.The output to this code is [2,2] and when i implement it along the axis 0,it outputs [1,1,1].I dont see the connection to this output with the scope of argmax method. I would appreciate a detailed insight to the argmax method.
