Density Plot
------------
Plots a 2-dimensional density plot.
.. object:: X Channel, Y Channel
The channels to plot on the X and Y axes.
.. object:: X Scale, Y Scale
How to scale the X and Y axes 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 Scale
Scale the color palette and 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.
