```python
import xarray as xr
import datatree
dt = datatree.open_datatree(""AQUA_MODIS.20220809T182500.L2.OC.nc"")
def fix_dimension_names(ds):
if 'pixel_control_points' in ds.dims:
ds = ds.swap_dims({'pixel_control_points': 'pixels_per_line'})
return ds
dt_fixed = dt.map_over_subtree(fix_dimension_names)
all_dsets = [subtree.ds for node, subtree in dt_fixed.items()]
ds = xr.merge(all_dsets, combine_attrs=""drop_conflicts"")
ds = ds.set_coords(['latitude', 'longitude'])
ds.chlor_a.plot(x=""longitude"", y=""latitude"", robust=True)
```

This model unfortunately breaks down when coordinate data are only present in one group. as in your dataset,"{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,605608998

I think somewhere there is a comment saying xarray could support searching for coordinate data in groups other than the one requested. So you could look into implementing that if interested.
Either way this would make a nice example notebook for the documentation.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,605608998
