    \brief The QBarSet class represents one set of bars in a bar graph.

    A bar set contains one data value for each category. The first value of a set is assumed to
    belong to the first category, the second one to the second category, and so on. If the set has
    fewer values than there are categories, the missing values are assumed to be located at the end
    of the set. For missing values in the middle of a set, the numerical value of zero is used.
    Labels for zero value sets are not shown.

    You can set a list of either \l [QML]{real} or \l [QML]{point}
    types as values.

    If you set a list of real types as values, they directly define the bar set values.

    If you set a list of point types as values, the x-coordinate of the point specifies its
    zero-based index in the bar set. The size of the bar set is the highest x-coordinate value + 1.
    If a point is missing for any x-coordinate between zero and the highest value,
    it gets the value zero.

    \qmlproperty list<variant> BarSet::values
    The values of the bar set. You can set a list of either \l [QML]{real} or \l [QML]{point}

    If you set a list of real types as values, they directly define the bar set values.

    If you set a list of point types as values, the x-coordinate of the point specifies its
    zero-based index in the bar set. The size of the bar set is the highest x-coordinate value + 1.
    If a point is missing for any x-coordinate between zero and the highest value,
    it gets the value zero.

    For example, the following bar sets have equal values:
    \code
        myBarSet1.values = [5, 0, 1, 5];
        myBarSet2.values = [Qt.point(0, 5), Qt.point(2, 1), Qt.point(3, 5)];
