**How to use this plot**

Make sure you have the required datafields (`number_of_wcb_trajectories`, `number_of_insitu_trajectories`, `number_of_mix_trajectories`)

You can use it as is by appending this code into your `mswms_settings.py`:

.. code-block:: python

    from mslib.mswms.mpl_hsec_styles import HS_LagrantoTrajStyle_PL_01
    register_horizontal_layers = [] if not register_horizontal_layers else register_horizontal_layers
    register_horizontal_layers.append((HS_LagrantoTrajStyle_PL_01, [next(iter(data))]))

**If you want to modify the plot**

1. Download this :download:`file <downloads/Top_PLLagrantoTraj.py>`

2. Put this file into your mswms_settings.py directory, e.g. `~/mss`

3. Append this code into your `mswms_settings.py`:

.. code-block:: python

   from Top_PLLagrantoTraj import HS_LagrantoTrajStyle_PL_01
   register_horizontal_layers = [] if not register_horizontal_layers else register_horizontal_layers
   register_horizontal_layers.append((HS_LagrantoTrajStyle_PL_01, [next(iter(data))]))
