TcxGridChartDataGroup Class
A Chart View data group.
Declaration
TcxGridChartDataGroup = class(
TcxGridChartItem
)Remarks
A data group determines categories that aggregate series values.
Data groups associated with data levels are called visible data groups. The visible data group that provides categories to render a chart is called active. Only one data group can be active at one time.
With the data level navigator, end-users can customize the level of detail in a chart by switching active data levels/groups and choosing their active values.
In unbound Chart Views, each data group is a TcxGridChartDataGroup object. To access all data groups created in a Chart View, use the View’s DataGroups collection.
In addition to the settings inherited from the base TcxGridChartItem class, the TcxGridChartDataGroup class introduces members that allow you to:
Activate a data group (Active).
Specify an active value for a data group and determine whether it has an active value assigned (ActiveValue and HasActiveValue).
Specify the position of the data level that corresponds to a data group within the data level navigator (DataLevel).
Specify the order in which to display categories and data markers once a group is activated (SortOrder).
To access a data group’s properties at design time, you need to select the data group either via the Component Editor or click the corresponding data level within the data level navigator.
