<blockquote>
<div><p>date, year, month, day, d, open, high, low, close,
volume, adjusted_close</p>
</div></blockquote>
<p>where d is a floating poing representation of date,
as returned by date2num, and date is a python standard
library datetime.date instance.</p>
<p>The name of this kwarg is a historical artifact. Formerly,
True returned a cbook Bunch
holding 1-D ndarrays. The behavior of a numpy recarray is
very similar to the Bunch.</p>
