XYGetScaleOffset

XYGetScaleOffset gets the scaling for the x- and y coordinates of the given dataset.

rvScaleOffset = XYGetScaleOffset(hData)

Return Value

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]

Parameters

hData

The handle of a dataset created with XYCreate or TYCreate.

Comment

XYGetData returns the scaled values. XYSetData sets scaled values.
