A submenu of commands used for displaying chromatograms in the background.

Set Background Chromatogram Displays the background chromatogram on the background of the Data Acquisition window. Invokes the Open Chromatogram dialog, in which you may select which of the measured chromatograms you would like to display on the background of the running analysis.
The background chromatogram is colored gray in order to prevent it from being mistaken with the measured signal. It will only be displayed after the measurement has been started.
Close Background Chromatogram Switches the display of the background chromatogram off.
Show Subtraction Chromatogram Determines whether the subtracted chromatogram defined in the Subtraction section of the method file (Method Setup - Advanced) will be displayed in the background of the Data Acquisition window. The checkmark will appear before the command if the display is activated.
Close Window Closes the Data Acquisition window.
