Oh... I am so sorry about this. This works as expected now. It's weird that using list seemed to have worked at some point. Thanks a lot for your help

Thanks. I upgraded to 2022.03.0

I am still getting the error

Perfect. Thanks for the clear explanation. This fixes my issue. Fabien

Thanks @fabienpaulot https://github.com/fabienpaulot -- this could probably use a better error message. The arguments passed to x and y must be dimension or coordinate names of the DataArray rather than DataArrays themselves. In your case you can assign xcntr and ycntr as coordinates of test and then plot:

test = test.assign_coords(x=xcntr.rename({'nxp': 'xh', 'nyp': 'yh'}), y=ycntr.rename({'nxp': 'xh', 'nyp': 'yh'})) test['nh4_stf'].plot.contourf(x='x', y='y', ax=ax, transform=ccrs.PlateCarree())

The renaming is necessary so the dimension names match that of test.

I am getting an error if I pass x and y
