Unless you are suggesting that this should be changed for all Cygwin
users, the best solution is for you to set these options before
instantiating the Gnuplot object:

>>> import Gnuplot
>>> Gnuplot.GnuplotOpts.gnuplot_command = 'gnuplot.exe'
>>> Gnuplot.GnuplotOpts.default_term = 'x11'
>>> g = Gnuplot.Gnuplot()
>>> ...
