\class QHorizontalBarSeries

\brief Series for creating horizontal bar chart.
QHorizontalBarSeries 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. QHorizontalBarSeries groups the data
from sets to categories, which are defined by a QStringList.
See the \l {HorizontalBarChart Example} {horizontal bar chart example} to learn how to create a horizontal bar chart.
