\brief Series for creating stacked bar chart.
\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.
