Description:
A Spectrum Object stores an NMR, MS, IR or other sort of spectrum. The spectrum is defined on a regular grid of x-axis values running from XLow to XHigh in steps of XSpacing. The y-values may be specified similarly, or may be arbitrary floating-point values. This is a graphical object, and doesn't store spectral information beyond that needed to display the spectrum.
The bounding box, XLow, and XSpacing properties are required, but a Spectrum has no required objects.
