The “upright” rectangle (in the intervals [0, 0.5] and [0, 2]) of points represents the data corresponding to category ""A"". However, it is colored in blue, which corresponds to category ""B"". The order of labels in the legend is correct in the sense that it conserves the order in the Dataset.
In the second image, the color assignment in the plot is correct – data corresponding to category ""A"" is still colored in blue but that now corresponds to category ""A"". The legend is now alphabetically ordered instead of conserving the order the category coordinate in the Dataset.

Here is my new example where, again, data of category ""A"" get colored as ""B"" and vice versa.
```python
import xarray as xr
import numpy as np
u = np.random.rand(50, 2, 2) * np.array([1, 2])
v = np.random.rand(50, 2) * np.array([1, 0.5])
ds = xr.Dataset(
{
""u"": ((""x"", ""foo"", ""category""), u),
""v"": ((""x"", ""category""), v),
},
coords={""category"": [""B"", ""A""], ""foo"": [1, 2]}
)
g = ds.plot.scatter(
y=""u"",
x=""v"",
hue=""category"",
col=""foo""
);
```
I am sorry for the confusion.
