DISPLAYING DATA
Overlay allows you to display up to nine 2D traces simultaneously in the same Data
Overlay
Window (see previously), on the same set of axes.
The Data Window in which you intend to display the overlaid traces must be in 2D
Display Mode. Only the data that was originally in that Data Window can be saved
or modified when the Data Window is active - you cannot, for instance, use the Data
Window to calibrate traces that have been added as overlays. The Data Windows
from which the 2D overlays are taken may be in any display mode.
Data Window (2D Display Mode, with overlaid traces)
To add an overlay, click the Add Overlay button on the Data Window. An 'Add
Add Overlay
Another Trace to Display' Dialog Box appears on screen. The selection list displays
the names of data sets that are already being displayed in a Data Window, or you
may select data that you have previously stored to disk (a standard Dialog box lets
you select the file). Buttons let you specify Signal, Background, or Reference
data, if these are contained in the data set you have selected for overlay.
