This question is not related to TBSplineSeries alone, it is valid for
all series:
GetYValue refers to the "true" values stored in the series or, more
exact, its ChartSource.These are the value the user had
added.GetImgYValue returns the values expressed in "image units",
usually, these are pixels on the screen, pixels in the bitmap etc.
