Hello all !
I'm sorry if my question is not clear, but I do not know ho to produce a
simple example.
I'm plotting the graph of an implicit given function (say x^2+y^2=3)
using Sage.
What I know it that
1. when I ask sage to plot implicit_plot( f==3,(x,-5,5),(y,-5,5) ),
Sage computes

If it can help, I have the following in a Sage terminal :
sage: var('x,y')
sage: F=implicit_plot(x**2+y**2==2,(x,-5,5),(y,-5,5),plot_points=100)
sage: F.matplotlib()
matplotlib.figure.Figure object at 0xbfb60ac
sage:
Your data are embedded in a Line2d object which is itself a child of an
Axes, itself child of the figure. Try:
Fig = F.matplotlib()
ax = Fig.get_axes()[0] # to get the first (and maybe only) subplot
line = ax.get_axes()[0]
xdata = line.get_xdata()
ydata = line.get_ydata()
