Thanks, Jeff. The hlines work fine. But the ylim doesn't change anything. I still get a plot that goes from 20 to 90 instead of 0 to 100. Here's my code. Please take a quick look and tell me where I have to put the ylim statement.
fig = figure(figsize=(6,2))
title('Dow Jones Industrials (^DJI) Relative Strength Index (RSI)', fontsize=8)months = MonthLocator(range(1,13,2), bymonthday=1)
monthsFmt = DateFormatter("%b '%y")bx = fig.add_subplot(111)
bx.grid(True)
bx.plot_date(dates, rsis, '-')bx.xaxis.set_major_locator(months)
bx.xaxis.set_major_formatter(monthsFmt)axhline(30,color='g')
axhline(70,color='r')fig.savefig('dow_30_rsi')
Carl: I can't run this, since the 'dates' and 'rsis' objects are not defined, but I'd try putting the ylim last, after the axhlines.
