Plotting

easysnowdata.plotting

Plotting helpers that read CF flag attributes (design contract §2.7).

Nothing here is required to use the data: the helpers build a ListedColormap + BoundaryNorm and a legend from flag_values / flag_meanings / flag_colors written by easysnowdata.processing.categorical, register named colormaps, and draw RGB quicklooks.

colormap_from_flags	Return (cmap, norm, table) for a categorical array's CF flags.
legend_handles	(handles, labels) for ax.legend from the CF flags (underscores → spaces).
categorical	Plot a categorical DataArray with one color per class and a legend.
register_colormap	Register a ListedColormap under name with matplotlib and return it.
rgb	Show a 0–1 RGB composite from easysnowdata.processing.rgb().
