5.9.2. Detector/Buffer
This command switches the active window spectrum and Status Sidebar displays between the last active Detector and the last active buffer. The Full and Expanded Spectrum Views display the data in histogram form. This command is duplicated by the accelerators <F4> and <Alt + 6>. You can also use the toolbar’s
Detector droplist.
5.9.3. Logarithmic
Logarithmic toggles the vertical scale of the
Spectrum display between the logarithmic and linear modes. This function is duplicated by Keypad</> and the Log/Linear Display button on the toolbar.

5.9.4. Automatic
Automatic switches the Expanded Spectrum View to a linear scale that is automatically adjusted until the largest peak shown is at its maximum height without overflowing the display. It also toggles the vertical scale of the spectrum display between the automatic and manual modes. If the logarithmic scale was enabled, the display is switched to linear. This function is duplicated by Keypad<*> and the Vertical Auto Scale toolbar button.
5.9.5. Baseline Zoom
When you select Baseline Zoom, the baseline of the spectrum displayed in the expanded view is always zero counts. In this mode, a checkmark is displayed beside the item name on the menu.
When Baseline Zoom is off (no checkmark beside the item name), the baseline can be offset to a higher value. This is useful to show small peaks on a high background. When the baseline is offset, the box in the Full Spectrum View is raised above the baseline to show the offset. This is duplicated on the toolbar.
5.9.6. Zoom In
Zoom In adjusts the horizontal and vertical scales in the Expanded Spectrum View to view a smaller portion of the spectrum. The vertical scale is divided by two and the horizontal scale is reduced by about
6% of the full horizontal scale. The current horizontal
