However, calling `set_boundary` at the end would leave the data unrestricted.

```python
import xarray as xr
import matplotlib.pyplot as plt
import matplotlib.path as mpath
import cartopy.crs as ccrs
import cartopy.feature as cfeature
import numpy as np

ds = xr.tutorial.load_dataset('air_temperature')

ax = plt.subplot(projection=ccrs.NorthPolarStereo())
# ax.set_boundary(circle, transform=ax.transAxes)  # works and ""cuts"" also the data as in the example above

data = ds.air.isel(time=0)

ax.pcolor(data.lon, data.lat, data, transform=ccrs.PlateCarree())

theta = np.linspace(0, 2*np.pi, 100)
center, radius = [0.5, 0.5], 0.5
verts = np.vstack([np.sin(theta), np.cos(theta)]).T
circle = mpath.Path(verts * radius + center)

ax.coastlines()
ax.gridlines()
ax.set_extent([-180,180, 50,90], crs=ccrs.PlateCarree())
ax.set_boundary(circle, transform=ax.transAxes)   # works for the axis border but not for the data

I should've mentioned that. On a single plot this works, but only iff you apply the `set_boundary` command before the data plotting, i.e.:

```python
import xarray as xr
import matplotlib.pyplot as plt
import matplotlib.path as mpath
import cartopy.crs as ccrs
import cartopy.feature as cfeature
import numpy as np

ds = xr.tutorial.load_dataset('air_temperature')

ax = plt.subplot(projection=ccrs.NorthPolarStereo())
ax.set_boundary(circle, transform=ax.transAxes)  # works

data = ds.air.isel(time=0)
p = data.plot(transform=ccrs.PlateCarree(),
            y=""lat"", x=""lon"",
            ax=ax
)

theta = np.linspace(0, 2*np.pi, 100)
center, radius = [0.5, 0.5], 0.5
verts = np.vstack([np.sin(theta), np.cos(theta)]).T
circle = mpath.Path(verts * radius + center)

ax.coastlines()
ax.gridlines()
ax.set_extent([-180,180, 50,90], crs=ccrs.PlateCarree())
# ax.set_boundary(circle, transform=ax.transAxes)   # wouldn't work
