Easy iteration over slices of a DataArray #266
Description
The DataArray object would benefit from functionality similar to iris.cube.Cube.slices. Given an array
[23]: data.coords
Out[23]:
Coordinates:
* sza (sza) float64 0.0 36.87 53.13 60.0 72.54 75.52 81.37 87.13 88.28
* vza (vza) float64 0.0 72.54
* raa (raa) float64 0.0 60.0 90.0 120.0 180.0
* wl (wl) float64 360.0 380.0 400.0 420.0 440.0
it would be nice to be able to do
for sl in data.slices(["raa", "wl"]):
# do magic with a DataArray of coordinates (sza, vza)

Right now we have the 1d version of
sliceswithgroupby, e.g.,(though the code does sort of implicitly assume that the values along the index are unique)
I agree, something like this would be nice. I think Iris now also has
slices_over, e.g.,data.slices_over(['sza', 'vza'])would be equivalent to your example, and it would be good to cover that case as well.max-sixty commentedon Jan 15, 2019
