Hi Nareto,

would you mind to write a simple and minimal example of your f(t) and plot options? This would be the best way to try to help you

Hello, I have to plot an exponential function with vertical asymptote
in point tc, but

plot(f(t), (tc  - e, tc + e));

gives me unreadable plots for any values of e - if e is to large the
curvature is not apreciable (i.e. the plot is confused with the axes)
but if it's too small I'm getting things like 40000 on the y axis.

So, how can I force the y axis range? I tried this but it doesn't
change anything:

P = plot(f(t));
P.set_range_axes(tc - 0.2, tc + 0.2, f(tc - 0.2), f(tc + 0.2));
show(P);

Question #2, how can I tell sage not to 'break' the axes? for example,

plot(1/(x + 3));

doesn't show me the last bit of the y axis, it ends approximately at
0.25


thanks for any help
Renato
