Unless I send this when I notice it, I'll forget to send it.
But I'm not so cold hearted as to hope for any response from
John during the early weeks of fatherhood!
If a plot makes use of both axhline() and axis(), then
axis() must come last or the results are not as expected.
Actually I have found it often desirable for axis to come
last, but I will simply raise the question of whether this
need---possibly surprising to a new user---might be
transcended.
fwiw,
Alan Isaac
PS Best wishes to John in his newest and most creative endeavor.
