FacetGrid.
facet_data
(self)¶Generator for name indices and data subsets for each facet.
The ints provide an index into the {row, col, hue}_names attribute,
and the dataframe contains a subset of the full data corresponding
to each facet. The generator yields subsets that correspond with
the self.axes.flat iterator, or self.axes[i, j] when col_wrap
is None.
