SRGraphStyle::SetUseMaxScale

inline voidSRGraphStyle::SetUseMaxScale(BOOLstyle, BOOLstyle)

Initializes the semaphore for use of maximum scale values

Defined in: SRGDat.h

Return Value

void

Parameters

style

TRUE to use maximum scales

style

TRUE to turn the scale limiting on

Remarks

When set, the display object which owns this style object will use the maximum and minimum scales stored in the m_dMaxRangeY and m_dMinRangeY members.
For display components, the effect depends on the ScaleLimit flag.
If SetScaleLimit(FALSE) and SetUseMaxScale(FALSE), axes are scaled to fit the data values (full autoscaling).
If SetScaleLimit(FALSE) and SetUseMaxScale(TRUE), the axis limits are fixed (no autoscaling).
If SetScaleLimit(TRUE) and SetUseMaxScale(FALSE), axes are autoscaled but the specified range is not exceeded (autoscaling with maximum limits).
If SetScaleLimit(TRUE) and SetUseMaxScale(TRUE), the data range is expanded, if necessary, to the specified limits (autoscaling with minimum limits).
Autoscaling with minimum limits can be used to avoid the problematic situation which occurs when all the data values have the same value.

Developer Notes

For Pie graphs, SetUseMaxScale(TRUE) and SetMinRangeX(dMin) can be used to prevent small wedges (smaller than dMin) from being labeled. If dMin is a negative number between 0 and -100, -dMin sets the limit as a percentage of the total pie.
