\class QGroupedBarSeries
\brief part of QtCommercial chart API.
\mainclass
sauimone
Fixed category handling of barcharts. Now the categories can be undefined. Updated documentation.
 r1208 QGroupedBarSeries represents a series of data shown as bars. The purpose of this class is to draw bars
as groups, where bars in same category are grouped next to each other. QGroupedBarSeries groups the data
from sets to categories, which are defined by a QStringList.
