Using the Mouse
The symbol ⌘ represents the Command key on macOS and the Alt Gr key on Windows.
The following operations do not require selecting a specific tool.
| Action | Details |
|---|---|
| Resize and Move the Plotting Area | Move the pointer near any of the margins.
When you see the hand-cursor, click and drag the margin. The margins can also be adjusted from Format > Overlay. |
| Move the 1D Plot Up and Down | Move the pointer near the zero-intensity line (the baseline). When you see the hand-cursor, click and drag. |
| Change the Position of the Scale(s) on the screen | Move the pointer near the scale. When you see the hand-cursor, click and drag to a new position. |
| Pan | Click below the scale and drag. Click at the right, in the case of the vertical scale. |
| Live Zoom (Mac only) | Right-click below the scale and drag. At the right, in the case of the vertical scale. Alternatively press the command key and use the scroll wheel. |
| Fit the tallest peak within the plot | Double-click the fragment containing the peak. |
| Select a Region | Click and drag. |
| Show the Full Spectrum | Triple-click (Mac only) or View > Full. |
| Create/Delete a Vertical Mark | ⌘-click Marks can be repositioned by dragging; when a 2D plot contains a single vertical mark, the corresponding trace is shown at the side of the plot. |
| Create/Delete a Horizontal Mark | Alt-click Marks can be repositioned by dragging; when a 2D plot contains a single horizontal mark, the corresponding trace is shown above the plot. |
| Delete All the Vertical Marks | ⌘-double-click |
| Delete All the Horizontal Marks | Alt-double-click |
You can also use the mouse wheel to amplify, deamplify and scroll horizontally. In a 2-D plot, move the pointer inside the plot to adjust its intensity scale (the projections remain the same) or over one of the projections to amplify it (the main plot and the other projection remain the same). On the Mac, you can temporarily disable the option “Mighty Mouse Can Scroll” with a modifier key (like the ⇧ key).
When you drag something, you can optionally hold the Shift key to restrict movements.
When a scale is positioned directly on a plot margin, dragging near that area may affect either the scale or the margin. The rule is simple: drag from outside the plot to move the scale; drag from inside the plot to move the margin.
Many common operations are also available through keyboard shortcuts.
In this case it is a shortcut for an operation
that can also be performed in another way, for example with a button or a menu item.
There are also a few rare operations that can only be performed with a key.
For some commands, Shift (⇧) increases the step size, while Control (Ctrl) reduces it.
For example, the plus key (+) increases the vertical scale by a factor of 2;
Shift-Plus by a factor of 5; and Control-Plus by a factor of 1.1.
If you hold a key down, its action is continuously repeated.
