TrajaDataFrame
--------------

A ``TrajaDataFrame`` is a tabular data structure that contains ``x``, ``y``, and ``time`` columns.

All pandas ``DataFrame`` methods are also available, although they may
not operate in a meaningful way on the ``x``, ``y``, and ``time`` columns.

.. inheritance-diagram:: traja.TrajaDataFrame

TrajaCollection
---------------

A ``TrajaCollection`` holds multiple trajectories for analyzing and comparing trajectories.
It has limited accessibility to lower-level methods.

.. autoclass:: traja.frame.TrajaCollection

.. automethod:: traja.frame.TrajaCollection.apply_all

.. automethod:: traja.frame.TrajaCollection.plot
