Comment(by wdj):
This applies to 4.1.alpha1 on an amd64 ubuntu 9.04 machine and passes all
tests except for three which seem unrelated (darwin_utilities,
random_tests, and the French programming tutorial).
{{{
sage: t = var("t")
sage: plot(heaviside(t)+2*heaviside(t-1),t,-5,5)
sage: P1 = plot(t*heaviside(t)+(2-t)*heaviside(t-1),t,-5,5)
sage: P2 = plot(heaviside(t)*cos(t),t,-5,5, linestyle="--",
rgbcolor=(1,0,0), thickness=3)
sage: show(P1+P2)
}}}
I like the fact that plotting like this works so well!
