|
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.
|
|
|
|
|
|
See the \l {PercentbarChart Example} {percent bar chart example} to learn how to create a percent bar chart.
