I have a pretty simple script working right now, and I'm still  
relatively new to python so if I'm going at this in a stupid way,  
please let me know.

right now it has the following:

            a_mag = Gnuplot.Data(w, cols=(1,6), inline=1)
            a_mag.set_option(title='Amide Dipole')
            a_mag.set_option(with='lines')

            mags.append(a_mag)

             s_mag = Gnuplot.Data(w, cols=(1,10), inline=1)
             s_mag.set_option(title='Side Chain Dipole')
             s_mag.set_option(with='lines')

            mags.append(s_mag)

when I use the command:
             g.plot(a_mag, s_mag)

everything works fine. I would like however to add or remove certain  
plots from within the script, but alas the command:

             g.plot(mags)

or
             g.plot(tuple(mags))

does not work. I get the following error messages:

Traceback (most recent call last):

     return multiarray.array(a, typecode, copy=0, savespace=savespace)

Any suggestions?

Thanks for any help,
