| \class QBarSet | ||||
| \brief part of QtCommercial chart API. | ||||
| QBarSet represents one set of bars. Set of bars contains one data value for each category. | ||||
| First value of set is assumed to belong to first category, second to second category and so on. | ||||
| If set has fewer values than there are categories, then the missing values are assumed to be | ||||
| at the end of set. For missing values in middle of a set, numerical value of zero is used. | ||||
