example/finance.py throws error
When I run example/finance.py from current master I see the below error.

```
/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/matplotlib/finance.py:485: MatplotlibDeprecationWarning: This function has been deprecated in 1.4 in favor of `quotes_historical_yahoo_ochl`, which maintains the original argument order, or `quotes_historical_yahoo_ohlc`, which uses the open-high-low-close order.
