Zoom Out
Zoom Out adjusts the horizontal and vertical scales in the Expanded Spectrum Window to view a larger portion of the spectrum. This command is duplicated by the Zoom Out button on the toolbar.
Undo Zoom In
This will undo or reverse the last Zoom In operation done with the rubber rectangle. It restores the display to the horizontal and vertical expansion before the Zoom In. It is not the same as
Zoom Out.
Full View
Full View adjusts the horizontal and vertical scaling to display the entire spectrum in the
Expanded Spectrum View.
Mark ROI
This allows you to mark a peak as an ROI by clicking and dragging the rubber rectangle across a portion of the spectrum, then selecting Mark ROI. If Show ROI Bars is on, the new ROI will be marked with the active ROI Bars until you either move to or create another ROI.
Clear Active ROI
This clears the ROI bits in all ROI channels that adjoin the channel containing the marker.
Show ROI Bars
These are vertical markers that indicate the lower and upper boundaries of each ROI in the spectrum. The ROI bars for an inactive/unselected ROI have solid fill; when you click an ROI to activate it (only one is active at a time), the bars for the active
ROI change to a diagonal fill (see Fig. 187). To display the
ROI bars, right-click in the expanded window to open the rightmouse-button menu, then click ROI Bars to checkmark it. To hide the ROI bars, click the command again to clear the checkmark.
