\brief The QHorizontalBarSeries class presents a series of data as horizontal bars grouped by
category.
This class draws data as a series of horizontal bars grouped by category, with one bar per
category from each bar set added to the series.
See the \l {Charts with Widgets Gallery} to learn how to create a horizontal bar chart.

\brief Presents a series of data as horizontal bars grouped by category.
The data is drawn as a series of horizontal bars grouped by category, with one bar per
category from each bar set added to the series.
The following QML code snippet shows how to create a simple horizontal bar chart:
