XYSetScaleOffset

XYSetScaleOffset sets the scaling for the x- and y-coordinates of the given dataset.

bool = XYSetScaleOffset(hData, rvScaleOffset)

Return Value

If the function succeeds, the return value bool is TRUE (1); otherwise it is FALSE (0).

Parameters

hData

The handle of a dataset created with XYCreate or TYCreate.

rvScaleOffset

rvScaleOffset is a real vector with 4 elements:

Value	Bedeutung
rvScaleOffset[1]	X-Scale Factor
rvScaleOffset[2]	X-Offset
rvScaleOffset[3]	Y-Scale Factor
rvScaleOffset[4]	Y-Offset

XOriginal = XOriginal * rvScaleOffset[1] + rvScaleOffset[2]
YOriginal = YOriginal * rvScaleOffset[3] + rvScaleOffset[4]

Comment

XYGetData returns the scaled values. XYSetData sets scaled values.
