Ahh, I see, you are doing a "2-d" line plot by doing a 3-d line plot
whose z values are always zero. The same trick works in Gnuplot.py:
import math, numpy
import Gnuplot
g = Gnuplot.Gnuplot()
theta = numpy.arange(-math.pi, math.pi, 0.1)
x = numpy.cos(theta)
y = numpy.sin(theta)
g.splot(
Gnuplot.Func('x*x + y*y'),
Gnuplot.Data(x,y, using='1:2:(0)', with_='line'),
)
or you can pass the zero data to gnuplot explicitly using something like
g.splot(
Gnuplot.Func('x*x + y*y'),
Gnuplot.Data(x,y,numpy.zeros(len(t)), with_='line'),
)
