New description:
The purpose of the ticket is be able to recompute plots in order to have
labels at given functions. You need to locate where the function text
should be applied to the function plot to be able to have labels for plots
like:
{{{
var('x');
x_cord = xmin;
f = x**2;
p = plot(f,x)+text(f,(x_cord,f(x_cord))
}}}
for one function.
Similarly for two functions (syntax may change):
{{{
g = x;
f = x**2;
p = plot(f,x);
x_cord = xmin;
(g + f) + text(f, (f,x_cord), g, (g,x_cord))
}}}
where the string prints the label for g, while "g" prints label only for
f.

The ticket [http://trac.sagemath.org/sage_trac/ticket/4342] seems to
consider the same problem but from the different perspective to solve it.
--
The recomputing would solve at least the following problem
{{{
# to increase the range of axis does not extend the plots
# we need to recompute the plot to do that
var('x')
p = plot(x**,x)
p.set_axes_range(-10,10,-10,10)
}}}
Milestone
1. to recompute the plot such that we can change ranges for plots
