BOOL CBCGPChartAxis::AddScaleBreak ( const CBCGPChartAxisScaleBreak scaleBreak,
BOOL  bCreateScaleParts = TRUE 
)

Parameters
scaleBreakA reference to a scale break to add.
bCreateScalePartsIf TRUE the axis will re-generate scale parts. Leave this as FALSE for subsecuent calls if you're adding several scale breaks (except the last call).
