|
11 | 11 | QBarSet represents one set of bars. Set of bars contains one data value for each category. |
|
12 | 12 | First value of set is assumed to belong to first category, second to second category and so on. |
|
13 | 13 | If set has fewer values than there are categories, then the missing values are assumed to be |
|
14 | 14 | at the end of set. For missing values in middle of a set, numerical value of zero is used. |
