If `by` is assigned, return a dictionary of DataFrames in which the key of dictionary is the values in groups. If `by` is not assigned, return input as is, and this preserves current status of iter_data. Parameters ---------- data : reformatted grouped data from `_compute_plot_data` method. kind : str, plot kind. This function is only used for `hist` and `box` plots. Returns ------- iter_data : DataFrame or Dictionary of DataFrames Examples -------- If `by` is assigned: >>> import numpy as np >>> tuples = [('h1', 'a'), ('h1', 'b'), ('h2', 'a'), ('h2', 'b')] >>> mi = pd.MultiIndex.from_tuples(tuples) >>> value = [[1, 3, np.nan, np.nan], ... [3, 4, np.nan, np.nan], [np.nan, np.nan, 5, 6]] >>> data = pd.DataFrame(value, columns=mi) >>> create_iter_data_given_by(data) {'h1': h1 a b 0 1.0 3.0 1 3.0 4.0 2 NaN NaN, 'h2': h2 a b 0 NaN NaN 1 NaN NaN 2 5.0 6.0} rrcli|]0}|jddj|kf1S)N)loccolumnsget_level_values).0colrlevels c/var/www/html/test/jupyter/venv/lib/python3.11/site-packages/pandas/plotting/_matplotlib/groupby.py z-create_iter_data_given_by..RsP     TXaaa66u==DD E   ) isinstancerrlevels)rrrs` @rcreate_iter_data_given_byr"sp^ v~~ dlJ / ////     <&u-   rbyr colsct|}||}g}|D]@\}}tj|g|g}||} || _|| At |d}|S)al Internal function to group data, and reassign multiindex column names onto the result in order to let grouped data be used in _compute_plot_data method.
