QStackedBarSeries represents a series of data shown as bars. All bars in same category are
|
|
|
stacked on top of each other. One QStackedBarSeries can contain multiple QBarSet data sets.
|
|
|
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.
