Comment(by jason):
A simpler example:
{{{
def multiple_of_pi(n,pos):
m = n*1.0/float(pi)
c=[i for i in convergents(m) if i.denominator()<12]
q=c[-1]
return '$%s$'%latex(q*pi)
from matplotlib.ticker import MultipleLocator, FuncFormatter
plot(sin(x), (x, -4, 4), tick_locator=MultipleLocator(float(pi/4)),
tick_formatter=FuncFormatter(multiple_of_pi))
}}}
