| 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. | ||||
