11.1.4.2. Zoom In
Zoom In adjusts the horizontal and vertical scales in the Expanded Spectrum Window to view a smaller portion of the spectrum. This command is duplicated by the Zoom In button on the toolbar.
11.1.4.3. 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.
11.1.4.4. 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.
11.1.4.5. Full View
Full View adjusts the horizontal and vertical scaling to display the entire spectrum in the
Expanded Spectrum View.
11.1.4.6. 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 (Section 11.1.4.8), the new ROI will be marked with the active ROI Bars until you either move to or create another
ROI. Use the Modify Active ROI command on the ROI menu (Section 11.1.3.4) to widen the
ROI boundaries, or click and drag the ROI bars to increase or decrease the number of channels in the ROI.
11.1.4.7. Clear Active ROI
This clears the ROI bits in all ROI channels that adjoin the channel containing the marker. This is the same as the Clear command on the ROI menu (Section 11.1.3.4).
11.1.4.8. 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. 322). To display the ROI bars, right-click in the expanded window to open the right-mousebutton menu, then click ROI Bars to checkmark it. To hide the ROI bars, click the command again to clear the checkmark.
