Assuming 'g' is your gnuplot instance:

g('set xrange [-4:2]')
g('set yrange [0:10]')

Open a gnuplot session in a separate terminal and use its builtin help. Once 
you figure out which commands you need interactively, you can just pass them 
to the python-controlled gnuplot by calling it as a function with the command 
you want in a string.
