Abstract
A method for graphically forming a difference spectrum from a sample spectrum and a reference spectrum on a computer system includes displaying an initial difference spectrum on the display the initial difference spectrum being equal to the sample spectrum, selecting a data point in the initial difference spectrum, having an associated wave number, with a relative pointing device on the display, moving the data point a measurable amount on the display with the relative pointing device, determining a scaling factor in response to the measurable amount and to a data point in the reference spectrum having the same associated wave number, scaling each data point in the reference spectrum by the scaling factor to form a scaled reference spectrum, determining the difference spectrum between the sample spectrum and the scaled reference spectrum, and displaying at least a portion of the difference spectrum on the display.
