Violin Plot
-----------

Plots a violin plot, which is a nice way to compare several distributions.

.. object:: X Variable

    The variable to compare on the X axis.

.. object:: Y Channel

    The channel to plot on the Y axis.
    
.. object:: Y Channel Scale

    How to scale the Y axis of the plot.
    
.. object:: Horizonal Facet

    Make multiple plots.  Each column has a unique value of this variable.
    
.. object:: Vertical Facet

    Make multiple plots.  Each row has a unique value of this variable.
    
.. object:: Color Facet

    Plot with multiple colors.  Each color has a unique value of this variable.
    
.. object:: Color Scale

    If **Color Facet** is a numeric variable, use this scale for the color
    bar.
    
.. object:: Tab Facet

    Make multiple plots in differen tabs; each tab's plot has a unique value
    of this variable.
    
.. object:: Subset

    Plot only a subset of the data in the experiment.
  
.. plot::
   :include-source: False
