Hello,

I think I'm missing something simple here. I tried looking at the documentation, but no luck. I'm trying to create DataArrays whose coordinates are two dimensional as follows

```python from xarray import DataArray import numpy as np

x_physical = DataArray(np.ones((2,2)), dims = ['x_logical', 'y_logical'])

y_physical = DataArray(np.ones((2,2)), dims = ['x_logical', 'y_logical'])

new_array = DataArray(np.zeros((2,2)), dims=['x_logical','y_logical'], coords=[x_physical, y_physical]) ``` trying to follow the multidimensional example in the docs.

This gives me a ValueError: 'x_logical' has more than 1-dimension and the same name as one of its dimensions ('x_logical', 'y_logical'). xarray disallows such variables because they conflict with the coordinates used to label dimensions.

I have tried multiple variants of this:

  • replace x/y_logical in the arguments to creating new_array with something else, which gives me a ValueError: dimensions ('x',) must have the same length as the number of data dimensions, ndim=2

and some other variants which in hindsight make no sense.

Is there something I'm missing, and is creating multidimensional DataArrays documented somewhere?

TIA, Joy
