Histogram Groups
A histogram group, as specified in the base class HistogramGroup, consists off a set of histogram that usually will be printed onto one canvas.
A class of type HistogramGroup is responsible for creating, deleting, filling, resetting, and drawing of its histograms. It also holds information about the detector groups and event groups for which the group should be active two unsigned int (Jeff L ).
When processing event from the event pool, the online monitoring is examining every histogram group whether its detector and event group match current event’s respective groups. Only if a match if found, the HistogramGroup is filled. The fill function is passed pointers to the evpReader and the to data: virtual bool fill(evpReader*, char* datap)
With every new run, a HistogramGroups reset() function is called.
