Re: [Gnuplot-py-users] Plotting a variable list?

This is easy using just Python features (no special support from 
Gnuplot.py required):

Under any Python version:

    apply(g.plot, plot_list)

Under recent Python versions (starting at 2.0?):

    g.plot(*plot_list)

Either of these takes the elements of the sequence as individual 
arguments to the g.plot() method.
