Notes
Zoom Preferences
1 If you go to Main Menu / Preferences you can select whether the zoom occurs centred on the spectrum or centered around the cursor/mouse position. For more information go to Zooming.
Peak picking
2 Peaks are picked for all visible contours in a display. To pick selectively only positive or negative peaks or only peaks in one spectrum, make sure only those contours/spectra are currently displayed. For more information on peak picking go to our Peak Picking Tutorial.
