        By default, it create n by column (default 3) number of subplot within a single figure. n is based on len(attribute_list)/column.

            attribute_list (list): (row_category_split = 0)list of column names to plot. Each column name is put under one plot

            group ('str'):          category option within a plot. Only avaliable for box plot. where the x-axis is group.
            dataset ('dataframe'):  attribute_list items, group and row_category_split_col must be present in the dataset.

            column_default (int): default 3. change the layout of the figure.
