Description

This tool is used to subtract a curve by another one. When the two datasets' (curves) coordinates are not consistent, the two curves will be interpolated or extrapolated first.

Examples

Import Gaussian.dat on \Samples\Curve Fitting folder.
Highlight column B and select Plot: Line: Line to plot a curve.
Click Analysis: Data Manipulation: Subtract Reference Data to open Subtract Reference Data dialog.
Select column C for Reference Data branch. And then click the OK button.

Then you can see a new curve is created.
