    -- An even simpler framework for creating 2D charts in Haskell.
    --
    -- The basic idea is to make it as easy to plot as octave, which means that
    -- you provide no more information than you wish to provide.  We provide
    -- four plotting functions, which differ only in their output.  One
    -- produces a "Layout1" that you can customize using other
    -- Graphics.Rendering.Chart functions.  The other three produce their
    -- output directly.  All three accept the same input and produce the same plots.
    --
    -- The plot functions accept a variable number of arguments.  You must
    -- provide a [Double] which defines the points on the x axis, which must
    -- precede any of the "y" values.  The y values may either be [Double] or
    -- functions.  After any given y value, you can give either Strings or
    -- PlotKinds describing how you'd like that y printed.
    --
    -- Examples:
    --
    -- > plotPDF "foo.pdf" [0,0.1..10] sin "- " cos ". " cos "o"
    --
    -- > plotPS "foo.ps" [0,0.1..10] (sin . exp) "- " (sin . exp) "o-"
