Hi, folks! Thank you for the awesome project!

Here is a minor enhancement for the plotting of slices.

Before this PR:

```python
import xarray as xr
import numpy as np

dset = xr.Dataset(
    data_vars=dict(
        var_a=((""a"", ""b""), np.array([[1,2], [3,4]]))
    ),
    coords=dict(
        a=(""a"", np.array([5, 6]), {""unit"": ""s""}),
        b=(""b"", np.array([7, 8]), {""unit"": ""s""})
    )
)
_ = dset.var_a.sel(a=5).plot(marker=""o"")
```

After this PR (note the title):

I did not add any tests, since this change did not break anything I am guessing it is not something being tested.
