Comment rouler l'axe de longitude
# To adjust coordinate labels or make axis cyclic or periodic,
# you can use the Shift() and/or roll() methods as shown below:
import xarray as xr
array = xr.DataArray([1, 2, 3, 4], dims="x")
# shift the coordinate 'x' (to the right) by 2
array.shift(x=2)
# roll the coordinate 'x' (toward the right) by 2
array.roll(x=2, roll_coords=True)
