r1208 | QPercentBarSeries represents a series of data shown as bars. The purpose of this class is to draw bars | ||
as stacks, where each bar is shown as percentage of all bars in that category. | ||||
QPercentBarSeries groups the data from sets to categories, which are defined by a QStringList. | ||||
