| 41 | \brief The QHorizontalPercentBarSeries class presents a series of categorized data as |
| 42 | a percentage of each category. |
| 43 | |
| 44 | This class draws data as a series of uniformly sized horizontally stacked bars, with one |
| 45 | bar per category. Each bar set added to the series contributes a single segment to each |
| 46 | stacked bar. The segment size corresponds to the percentage of the segment value compared |
| 47 | with the total value of all segments in the stack. |
| 48 | Bars with zero value are not drawn. |
| 49 | |
| 50 | See the \l {HorizontalPercentBarChart Example} {horizontal percent bar chart example} to learn |
| 51 | how to create a horizontal percent bar chart. |
