Additional Elements
=======================================

Additional functionality can be added to your stratigraphic logs using the methods described below. These methods are called on an existing ``LogObject`` instance after plotting the log, for example:

.. code-block:: python

    import stratapy as sp
    log = sp.load('my_log.csv')
    log.plot()
    log.add_chronostratigraphy()

They enable rapid enhancement of your logs with commonly used features without needing to manually create and position additional axes or elements, such as chronostratigraphy from the International Commission on Stratigraphy, which automatically aligns with your log's age range.
