It might also make sense then to implement all numpy-like constructors for DataArray, plus the empty(), which is typically faster for larger arrays:

  • .full() (kind of what's suggested here)
  • .ones()
  • .zeros()
  • .empty()

This should be trivial to implement.

Hi, I am also looking for a solution to create an "empty" xarray (filled with some default value, say, 0 or NaN) whose size gets automatically determined by its coordinates (which are passed to the DataSet constructor as a dict). Has there been any progress since the original post by andreas-h?

    "total_count": 0,
    "+1": 0,
    "-1": 0,
    "laugh": 0,
    "hooray": 0,
    "confused": 0,
    "heart": 0,
    "rocket": 0,
    "eyes": 0

This seems too fundamental a feature to close unresolved. I am sure others will encounter the same need and will create duplicate issues.
