dict(xarray.DataArray([1, 2]).chunk().dask_graph()) { ('xarray-<this-array>-7e885b8e329090da3fe58d4483c0cf8b', 0): (<function dask.array.core.getter(a, b, asarray=True, lock=None)>, 'xarray-<this-array>-7e885b8e329090da3fe58d4483c0cf8b', (slice(0, 2, None),)), 'xarray-<this-array>-7e885b8e329090da3fe58d4483c0cf8b': ImplicitToExplicitIndexingAdapter(array=NumpyIndexingAdapter(array=array([1, 2]))) } There is no reason why this should be any more complicated than da.from_array: dict(da.from_array(np.array([1, 2]), chunks=2).dask_graph()) { ('array-de932becc43e72c010bc91ffefe42af1', 0): (<function dask.array.core.getter(a, b, asarray=True, lock=None)>, 'array-original-de932becc43e72c010bc91ffefe42af1', (slice(0, 2, None),)), 'array-original-de932becc43e72c010bc91ffefe42af1': array([1, 2]) } ``` da.from_array itself should be simplified - see twin issue https://github.com/dask/dask/issues/3556
