Functions

add_tile_coordinates(df: DataFrame, x_coord: str = 'group_id', y_coord: str = 'period', include_f_block: bool = True, wide_layout: bool = False) → DataFrame

Calculate coordinates for the tile centers

Parameters:

• df – dataframe

• x_coord – attribute to use as x coordinate

• y_coord – attribute to use as y coordinate

• wide_layout – Show the long version of the periodic table with the f block between the s and d blocks

• include_f_block – Show the elements from the f block

colormap_column(elements: DataFrame, column: str, cmap: str = 'RdBu_r', missing: str = '#ffffff')

Return a new DataFrame with the same size (and index) as elements with a column cmap containing HEX color mapping from cmap colormap.

Parameters:

• elements – DataFrame with the data

• column – Name of the column to be color mapped

• cmap – Name of the colormap, see matplotlib.org

• missing – HEX color for the missing values (NaN or None)

create_vis_dataframe(x_coord: str = 'group_id', y_coord: str = 'period', include_f_block: bool = True, wide_layout: bool = False)

Base DataFrame for visualizations

Parameters:

• x_coord – attribute to use as x coordinate

• y_coord – attribute to use as y coordinate

• include_f_block – show the elements from the f block

• wide_layout – show the long version of the periodic table with the f block between the s and d blocks
