Thanks. I didn't noticed it while reading sage/plot/plot.py.

It's very simple : if i type
plot? under 3.1.1 i get the help page which contains the following section :
PLOT OPTIONS:
The plot options are
plot_points -- the number of points to initially plot before
doing adaptive refinement
plot_division -- the maximum number of subdivisions to
introduce in adaptive refinement.
max_bend -- parameter that affects adaptive refinement
xmin -- starting x value
xmax -- ending x value
color -- an rgb-tuple (r,g,b) with each of r,g,b between 0 and 1, or
a color name as a string (e.g., 'purple'), or an HTML
color such as '#aaff0b'.
The two options named xmin and xmax are not valid options.
(as in
sage: plot(exp,xmin=-1,xmax=3)
)
As William said that the plot function has been completely rewritten,
it might be that all this is unnecessary noise and i apologize
sincerely for it.
I am writing a tutorial in french and i wanted to cover all possible options...
Thanks for your patience
