\class QPercentBarSeries

\brief Series for creating percent bar chart.
\mainclass
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.
