\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.
