I was computed Riemann's analytic formula for pi(X), and was disturbed it
wasn't converging to pi(X). It turned out that the function in Sage for a
while for plotting prime_pi is buggy! For example, try this:
{{{
sage: prime_pi.plot(5,10).show(gridlines='minor',frame=True)
sage: prime_pi(8)
4
}}}
You'll see a plot that has a horizontal line at height 5 on it.
This is very bad and embarrassing!
