\class QPercentBarSeries
\inmodule QtCharts
\brief The QPercentBarSeries class presents a series of categorized data as
a percentage of each category.
This class draws data as a series of uniformly sized vertically stacked bars, with one
bar per category. Each bar set added to the series contributes a single segment to each
stacked bar. The segment size corresponds to the percentage of the segment value compared
with the total value of all segments in the stack.
Bars with zero value are not drawn.
See the \l {Charts with Widgets Gallery} to learn how to create a
percent bar chart.
