Comment (by ppurka):
It is not a problem with loglog. There is the same problem with normal
plots.
{{{
sage: var('n')
sage: plot([n^2,exp(n)], xmin=1, xmax=10^5, ymin=1,ymax=10^10)
verbose 0 (2395: plot.py, generate_plot_points) WARNING: When plotting,
failed to evaluate function at 198 points.
verbose 0 (2395: plot.py, generate_plot_points) Last error message: ''
}}}
FYI, the change to loglog/semilog* scale happens only during the very end
when `show()` is called. This happens ''after'' the generation of the plot
points. Though I can't understand why semilogy is working fine for you
(you still get the warnings though).
