title: matplotlib.finance.quotes_historical_yahoo_ohlc vs. quotes_historical_yahoo_ochl
body: <p>Can anyone explain the difference between matplotlib.finance.parse_yahoo_historical_ochl and matplotlib.finance.parse_yahoo_historical_ohlc? What do ohlc and ochl stand for?
  The documentation at <a href="http://matplotlib.org/api/finance_api.html" rel="nofollow">http://matplotlib.org/api/finance_api.html</a> is not particularly helpful in this regard.</p>
