What is your issue?

If plotting a scatter plot with an unfilled marker, matplotlib raises a UserWarning. Consider this MWE:

```python import warnings

import numpy as np import xarray as xr

warnings.filterwarnings("error")

ds = xr.Dataset({"a": ("dim", np.arange(3, 10))}, {"dim": np.arange(7)}) ds.plot.scatter(x="dim", y="a", marker="x") ```

Running this with matplotlib 3.6.2 yields:

Traceback (most recent call last): File "/my/path/test.py", line 9, in <module> ds.plot.scatter(x="dim", y="a", marker="x") File "/my/path/.venv/lib/python3.9/site-packages/xarray/plot/accessor.py", line 1071, in scatter return dataset_plot.scatter(self._ds, *args, **kwargs) File "/my/path/.venv/lib/python3.9/site-packages/xarray/plot/dataset_plot.py", line 916, in scatter return da.plot.scatter(*locals_.pop("args", ()), **locals_) File "/my/path/.venv/lib/python3.9/site-packages/xarray/plot/accessor.py", line 305, in scatter return dataarray_plot.scatter(self._da, *args, **kwargs) File "/my/path/.venv/lib/python3.9/site-packages/xarray/plot/dataarray_plot.py", line 1002, in newplotfunc primitive = plotfunc( File "/my/path/.venv/lib/python3.9/site-packages/xarray/plot/dataarray_plot.py", line 1277, in scatter primitive = ax.scatter(*[p.to_numpy().ravel() for p in plts], **kwargs) File "/my/path/.venv/lib/python3.9/site-packages/matplotlib/__init__.py", line 1423, in inner return func(ax, *map(sanitize_sequence, args), **kwargs) File "/my/path/.venv/lib/python3.9/site-packages/matplotlib/axes/_axes.py", line 4571, in scatter _api.warn_external( File "/my/path/.venv/lib/python3.9/site-packages/matplotlib/_api/__init__.py", line 363, in warn_external warnings.warn(message, category, stacklevel) UserWarning: You passed a edgecolor/edgecolors ('w') for an unfilled marker ('x'). Matplotlib is ignoring the edgecolor in favor of the facecolor. This behavior may change in the future.
