easysnowdata.plotting.legend_handles

easysnowdata.plotting.legend_handles(obj: DataArray | dict[str, Any], *, present: set[Any] | None = None) → tuple[list[Any], list[str]]

(handles, labels) for ax.legend from the CF flags (underscores → spaces).

present restricts the legend to those flag values (the classes that actually occur in the plotted array).
