I just added `ax.grid(False)` but maybe we just want whatever is the default of matplotlib?

```python
import xarray as xr

airtemps = xr.tutorial.open_dataset(""air_temperature"")
air = airtemps.air - 273.15
air.attrs = airtemps.air.attrs
air.attrs[""units""] = ""deg C""

air2d = air.isel(time=500)
fig, axs = plt.subplots(2,1)
air2d.plot(ax=axs[0])  # No grid.
air2d.plot(ax=axs[1])  # With grid.
axs[1].grid(True)
```
