Column group fill ratio for series that determines the amount of place for one column group (for more information about column groups, see ShouldGroupColumns). For example, if this fill ratio is 1.0, columns in the group are sticked together with no gaps between them. If the fill ratio is 0.5, columns in the group have gaps and the total width of the gaps is equal to the total width all columns in the group. The default value is 1.0. The difference from FillRatio is that FillRatio deals with the gap between column groups and ColumnGroupFillRatio is responsible for the gap between columns inside the group.
