For just setting tables and line types and stuff you don't have to
extend the PlotItem interface directly; you can use the Data class
which is a type of PlotItem already customized for array data.

There are many examples in demo.py about how to use the Data class.
For example,

    x = arange(10, typecode=Float)
    y1 = x**2
    d = Gnuplot.Data(x, y1,
                     title='calculated by python',
                     with='points 3 3')

So for your example,

> #!/usr/bin/python
> 
> import Gnuplot, Gnuplot.funcutils

> X = []
> Y = []
> for x in range(32):
>    X.append((x, 2*x ))
>    Y.append((x, 3*x ))
> 
> g = Gnuplot.Gnuplot(debug=1)
> 
> g.plot(X, Y)
> raw_input('Please press return to continue...\n')

You would do something like the following (untested):

g.plot(
    Gnuplot.Data(X, title='This is the X dataset', with='linespoints'),
    Gnuplot.Data(Y, title='Some more data', with='points 2 5'),
    )

Please subscribe.  The list has an archive but since the list is very
new there are only a few messages in it.
