4.3. The Toolbar
The row of buttons below the menu bar provides convenient shortcuts to some of the most common GammaVision commands.
The Recall button retrieves an existing spectrum file. This is the equivalent of selecting
File/Recall from the menu.
Save copies the currently displayed spectrum to disk. It duplicates the commands
File/Save or File/Save As... (depending on whether the spectrum was recalled from disk, and whether any changes have been made to the spectrum window since the last save).
Start Acquisition starts data collection in the current Detector. This duplicates
Acquire/Start and <Alt + 1>.
Stop Acquisition stops data collection. This duplicates Acquire/Stop and <Alt + 2>.
Clear Spectrum clears the detector or file spectrum from the window. This duplicates
Acquire/Clear and <Alt + 3>.
List Mode toggles the current Detector between PHA and LIST modes. This duplicates
Acquire/List Mode. An indicator in the upper right of the Full Spectrum View shows the current data acquisition mode.
List Data Range lets you retrieve a specified time slice of data from a
.LIS
file in a buffer window (Section 5.4.2). This duplicates Calculate/List Data Range....
Mark ROI automatically marks an ROI in the spectrum at the marker position, according to the criteria in Section 5.8.4. This duplicates ROI/Mark Peak and <Insert>.
Clear ROI removes the ROI mark from the channels of the peak currently selected with the marker. This duplicates ROI/Clear and <Delete>.
The next section of the toolbar (Fig. 45) contains the buttons that control the spectrum’s vertical scale. These commands are also on the Display menu. In addition, vertical scale can be adjusted by zooming in with the mouse (see Section 4.4.3).

Vertical Log/Lin Scale switches between logarithmic and linear scaling. When switching from logarithmic to linear, it uses the previous linear scale setting. Its keyboard duplicate is Keypad</>.
Vertical Auto Scale turns on the autoscale mode, a linear scale that automatically adjusts until the largest peak shown is at its maximum height without overflowing the display. Its keyboard duplicate is Keypad<*>.
The field to the left of these two buttons displays LOG if the scale is logarithmic, or indicates the current vertical full-scale linear value.
The horizontal scaling section (Fig. 46) follows next. It includes a field that shows the current window width in channels, and the Zoom In, Zoom Out, Center, and Baseline Zoom buttons.
These commands are also on the Display menu. In addition, horizontal scale can be adjusted by zooming in with the mouse
(see Section 4.4.3).
Fig. 46. Horizontal Scaling
Section of Toolbar.
Zoom In decreases the horizontal full scale of the Expanded Spectrum View according to the discussion in Section 4.2, so the peaks appear “magnified.” This duplicates Display/
Zoom In and Keypad<+>.
Zoom Out increases the horizontal full scale of the Expanded Spectrum View according to the discussion in Section 4.2, so the peaks appear reduced in size. This duplicates
Display/Zoom Out and Keypad<
!>.
Center moves the marker to the center of the screen by shifting the spectrum without moving the marker from its current channel. This duplicates Display/Center and
Keypad<5>.
Baseline Zoom keeps the baseline of the spectrum set to zero counts.
The remaining buttons allow you to access the principal sample analysis functions.
Sample Type Settings opens the dialog that controls the current analysis settings (see
Section 5.5.1.1). This duplicates the Sample Type... command on the Analyze/Settings submenu.
