\mainclass

|
|
|
QStackedBarSeries represents a series of data shown as bars. The purpose of this class is to draw bars
|
|
|
as stacks, where bars in same category are stacked on top of each other.
|
|
|
QStackedBarSeries groups the data from sets to categories, which are defined by QStringList.
|
|
|
|
|
|
See the \l {StackedbarChart Example} {stacked bar chart example} to learn how to create a stacked bar chart.
