This is the repr for a DataArray with 7 coordinates and 5 dimensions. Do we agree this should be shorter?

Yes, I agree!

Right now, we outsource the repr for DataArray values by calling NumPy. So fixing this would entail either forking the formatting logic from NumPy or adding our own wrapper.

One way to do this might to use np.set_printoptions to adjust edgeitems (using something like this context manager), conditional on the dimensionality of the array.

I wonder if there should be a repr of values at all. I actually like the way xray displays netcdf variables when they are not yet read out of the file. See:

netcdf = xray.open_dataset('./data/ERA-Int-MonthlyAvg-4D-UVWZ.nc')
netcdf.z
<xray.DataArray 'z' (month: 12, level: 15, latitude: 241, longitude: 480)>

  * level      (level) int32 50 100 150 200 300 400 500 600 700 750 800 850 ...
  * month      (month) int64 1 2 3 4 5 6 7 8 9 10 11 12
  * longitude  (longitude) float32 -180.0 -179.25 -178.5 -177.75 -177.0 ...
