| \brief The QHorizontalPercentBarSeries class presents a series of categorized data as |
| a percentage of each category. |
| |
| This class draws data as a series of uniformly sized horizontally 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 {HorizontalPercentBarChart Example} {horizontal percent bar chart example} to learn |
| how to create a horizontal percent bar chart. |
