115979105 MDU6SXNzdWUxMTU5NzkxMDU= 652 ENH: Apply numpy function to named axes 5635139 closed 0     2 2015-11-09T22:11:19Z 2015-11-10T16:18:24Z 2015-11-10T16:18:24Z MEMBER      

I'm currently transitioning sequences of pandas Panels over to xray Datasets. Part of our process applies a set of functions to Panels; for example:

python panel = panel.apply(lambda x: x.rank(ascending=False), axis=(1, 2)) df = np.nanpercentile(panel, q=75, axis=2)

One of the benefits of xray is the clarity that comes from named axes. Is there a way of applying a function over named axes? For example:

python result = data_array.apply(np.argsort, axis=('Risk', 'Dates')) result = data_array.apply(np.nanpercentile, axis='Dates')
