r2690 | 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. | ||||
