Following chapter describes how to copy a modified chromatogram into a new one without changing the original chromatogram. For example we set up new Offset of Y-axis and this modification is about to saved in new chromatogram and want to keeping the original chromatogram unchanged.
- Open your chromatogram that you want to work with.
- In Chromatogram window click Display - Properties to open Graph Properties and go to Signals tab.
- Into Field Y Offset ⓐ write down value of desired offset in mV, in this example we choose 333 mV, and click OK button.
- Select Chromatogram - Overlay - Mathematics... and the Mathematical Operations window will open.
- Select Copy option ⓑ. Check Save as Chromatogram ⓒ, name the new chromatogram ⓓ and click the OK button.
- Both chromatograms will be displayed in overlay mode.
- Restore the original chromatogram by navigating to Graph Properties - Signals as in step 2.
- Select the original chromatogram ⓔ, click Original button ⓕ and close the dialog by clicking OK.
- Both chromatograms will be displayed in overlay mode as shown in the next image.
