Spectrum_DataPoint Property

CDXML Name:temp_SpectrumDataPoint
CDX Constant Name:kCDXProp_Spectrum_DataPoint
CDX Constant Value:0x0A86
Data Size:FLOAT64
Property of objects:kCDXObj_Spectrum
First written/read in:ChemDraw 5.0
Required?Required for spectra


The Y-axis values for the spectrum. It is an array of double values corresponding to X-axis values.

ChemDraw supports only those spectrum types with evenly-spaced X values. Accordingly, this property stores only the Y-coordinate values. Corresponding X-coordinate values can be calculated via the kCDXProp_Spectrum_XLow and kCDXProp_Spectrum_XSpacing properties.

This property is used explicitly only for CDX files. In CDXML files, the corresponding data is stored within the Spectrum object directly, as #PCDATA
