Functions ========= Functions are used to transform, combine, and perform computations on :term:`series` data. Functions are applied using the Composer interface or by manipulating the ``target`` parameters in the :doc:`Render API `. Usage ----- Most functions are applied to one :term:`series list`. Functions with the parameter ``*seriesLists`` can take an arbitrary number of series lists. To pass multiple series lists to a function which only takes one, use the :py:func:`group` function.
