\class QHorizontalPercentBarSeries

\brief Series for creating horizontal percent bar chart.
\mainclass
QHorizontalPercentBarSeries 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.
QHorizontalPercentBarSeries groups the data from sets to categories, which are defined by a
QStringList. Bars with zero value are not drawn.
See the \l {HorizontalPercentBarChart Example} {horizontal percent bar chart example} to learn
how to create a horizontal percent bar chart.
