\brief Series for creating percent bar chart. | ||||
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. | ||||
Bars with zero value are not drawn. | ||||
See the \l {PercentbarChart Example} {percent bar chart example} to learn how to create a | ||||
percent bar chart. | ||||
