Description
This tool is used to subtract one curve from another. When the two datasets' coordinates differ, the two curves will be interpolated or extrapolated with before subtraction occurs.
Examples
- Import Gaussian.dat on \Samples\Curve Fitting folder.
- Highlight column B and select Plot > Basic 2D : 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.
