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.
