This property selects the number of groups to be made visible in a graph. When this property is set to a value greater than zero, you may use the ScrollOffsetGroups property to define the first group to be made visible.
Syntax:
setViewableGroups(value);
value = getViewableGroups();
where:
Is any integer between 0 and the number of groups in the data that defines the graph. 0 (show all groups) is the default.
Example:
setViewableGroups(1);
setDataScrollerPresenceGroups(0);
setDepthAngle(0);
setDepthRadius(0);
setViewableGroups(3);
Note: The setDataRange() method can also be used to set the number of groups to be made visible in a graph. It establishes the range of data that is used in a graph.
See ScrollOffsetGroup, ViewableGroupsStock, ViewableSeries, ViewableSeriesStock, setDataRange().
