Detrend xarray DataArrays using polyfit
Hey! This was a useful snippet of code for easy detrending, but I just wanted to say that it doesn't work as it is — when you pass 'dim' to xarray.polyval, it only reads a string, but it needs a coordinate type. I made it work by changing line 6 to:
fit = xr.polyval(da[dim], p.polyfit_coefficients)
Thanks for sharing!
