Accept xarray DataArray

[philippjfr]

Currently the xarray interface only supports an xr.Dataset, however a user often has a simple xr.DataArray so the interface should be able to accept a DataArray and automatically wrap it in a Dataset so it can interface with it. This avoids the user from having to do something like:

hv.Dataset(xr.Dataset({'value': xarr}))

[jlstevens]

So after this proposal is implemented, you will simply need hv.Dataset({'value': xarr}) presumably?

If so, this proposal makes perfect sense to me. Though is there anything else that might be of interest to HoloViews that is passed as an argument to the Dataset constructor?

[philippjfr]

No, it will just be:

hv.Dataset(xarr)

where the xr.DataArray should specify the name of the data variable.

[jlstevens]

Ok, that also makes sense. If there really is no other information HoloViews needs from the xr.Dataset then I imagine that this proposal will make things much more convenient for xarray users.

This has been supported since #894. Closing.
