SRGraph::m_bSignificantChange
BOOL SRGraph::m_bSignificantChangeTRUE after a SetSignificantChanges command
Remarks
The signficant change system allows the graph to process data faster by only updating items
when they have changed. All of the components in the component list look at their own
significant change flag before the draw cycle commences. If the flag is TRUE, the component
completely redraws all of its elements and updates all of its labels.
