Using Graphing Tools & Keyboard Shortcuts

Graphing Tools

The following table describes each of the graphing-related tools available in Graph View.

Depending on the type of data you are viewing, some of these buttons may be unavailable or they may change to reflect options that suit your current display.

Important! These buttons ONLY appear when you are in Graph View.

Most of the graphing functions can be performed by clicking a toolbar button or by making a selection from the Graph menu. There are also keyboard shortcuts and hotspots you can use on graphs. Additionally, you can use the Graph Remote Control to perform some common actions quickly, such as switching between acceleration and velocity.

Many of your graphing tool selections are retained as preferences so you do not have to reset your view as you navigate the tree.

Graphing Toolbar Button

Alternative Access
from Graph Menu


Toggle Add/Replace Mode


Graph>Add mode>Replace Data In Graph

Graph>Add mode>Add Data to Existing Graph

When in Add mode, selected data is added to the existing data in the graph.

When in Replace mode, data is first cleared from the graph before the new data is graphed.

Note: This tool is only enabled when you are viewing routine (survey) data. It is not enabled when you view advanced tests configured in the field.

Data Type
(other buttons appear
depending on the data)


Graph>Data type>Spectra

Graph>Data type>Cepstrum

Graph>Data type>Waveforms

Graph>Data type>Autocorrelation

Graph>Data type>Overalls

Graph>Data type>Phase

You can also use keyboard shortcuts to display different data types: S (spectral), C (cepstrum), W (waveform), A (autocorrelation), O (overall), and P (phase).

Allows you to view different types of data.

Only data types that have been enabled for the current location are available.

Note: If you select a process point in the tree, a trend of that data appears.

Change Format


Graph>Format>Single Graph

Graph>Format>Triaxial Graph

Graph>Format>Double Triaxial Graph

Graph>Format>Orbit Graph

Graph>Format>Single Circular Graph

Graph>Format>Triaxial Circular Graph

You can also use keyboard shortcuts to change graph format: 1 (single), 3 (triax), 6 (double triax), 2 (orbit), 5 (single axis circular), and 4 (triax circular).

Changes view between single, triaxial, and double triaxial formats; and when time waveform is selected, between orbit, single circular, and triaxial circular formats.

Note: When viewing Bode advanced test data, single and triaxial Nyquist formats are available via the Change Format toolbar button and the Graph>Format menu.

Change Layout





You can also use keyboard shortcuts to toggle between layouts. Use Ctrl+W to toggle between waterfall and single layouts; use Ctrl+O to toggle between overlay and single layouts.

When viewing a waterfall plot of time waveform data, press the J key on your keyboard to toggle between the following waveform trend parameters: Trend of Crest Factor, Trend of Symmetry, Trend of Peak-to-Peak, Trend of RMS.

You can also use the up and down arrow keys ▲▼  to move between graphs on waterfall or overlay plots.
Toggles between single, waterfall, and overlay plot modes.

Change Axis




Allows you to choose one of the available axes. The options available use the nomenclature specified in the database (for example, RTA, VHA, or XYZ).

Change Range


Graph>Range>Low Range

Graph>Range High Range

Graph>Range>Demod Range

You can also use keyboard shortcuts to change range: L (low range), H (high range), and D (demod range).
Toggles between displaying low, high, and demod frequency ranges.

Overlay Averages


Graph>Overlay Baseline Spectra>No Baseline Spectrum Overlay

Graph>Overlay Baseline Spectra>Overlay Average Baseline Spectrum

Graph>Overlay Baseline Spectra>Overlay One Sigma Baseline Spectrum

Graph>Overlay Baseline Spectra>Overlay Average and One Sigma Spectra

You can also press Ctrl+B on your keyboard to toggle through the available options.
Specifies how you want averages displayed. Available choices are no overlay, average overlay, average + one sigma overlay, or average and average + one sigma (two data sets).



Graph>View Toolbox Opens the Analysis Tools dialog box so you can specify harmonic and sideband cursors, set machine and spectra speed, and modify the forcing frequencies.

Set Graph Properties



Graph>View Graph Preferences Opens a dialog box so you can change the properties of the current graph, including scale, units, and color. The data type displayed determines which properties are available.

Select Latest/Previous/etc.


Graph>Data displayed>Latest Data

Graph>Data displayed>Previous Data

Graph>Data displayed>Latest + Previous

Graph>Data displayed>All Available Data

Graph>Data displayed>Show No Data - Averages Only

Graph>Data displayed>Select Date from List

You can also use keyboard shortcuts to select the test data you want displayed: ] (latest), [ (previous), \ (latest + previous). The other options do not have keyboard shortcuts.

Allows you to select the data you want to see based on date. You can choose the current data, previous data, latest and previous, all test data, no test data (for displaying only the average baseline), and select tests only. You can use Shift+click and Ctrl+click to select multiple test dates.

All of these buttons are enabled when viewing routine survey data in Graph View. However, if you select Advanced Tests or All from the associate drop‑down list, (see the next item in this table), only the Select Date from List button is enabled. This is because special tests and routine data cannot be graphed simultaneously, nor can different types of advanced tests.

Select Test Type


You can use keyboard shortcuts to select a test type: 0 (All Data), 9 (Advanced Tests), and 8 (Survey).

Select the type of tests you want to be included in the available data.

This drop-down list only appears when you click the Select Latest/Previous/etc. buttons.

  • All Data. Displays all tests, both routine survey tests and advanced tests that were configured via the More Data button on your TRIO.
  • Advanced Tests. Only special tests configured in the field on a TRIO via the More Data button are included.
  • Survey. Displays routine data collected using the machine/location specifications in the database. This is the default option.

Harmonics Toggle


Harmonics may be toggled on and off by pressing the Ctrl+H key on the keyboard.
Harmonics may also be set via the Harmonics tab of the Toolbox. You can also use the Graph Remote Control to see harmonic families.
Toggles between harmonic marker modes: off, on, and track cursor.

Center Frequency Toggle



Pressing Ctrl+T on the keyboard toggles sideband cursor tracking between the center and sideband frequency.
Center frequency tracking may also be turned on via the Sidebands tab of the Toolbox.
Toggles between center marker modes: on, off, and track cursor.

Sidebands Toggle


Sidebands may be toggled on and off by pressing the Ctrl+S key on the keyboard.
Sidebands may also be set via the Sidebands tab of the Toolbox . You can also use the Graph Remote Control to see sideband families.

Toggles between sideband marker modes: on and track cursor.

This button is disabled if the Center Frequency button is toggled to off.

Kill Highlighted Peaks


N/A Removes peaks from the graph that have harmonic or sideband markers on them. They are removed only from the displayed graph—not deleted from the data stored in the database.

Toggle Reference Cursor


The reference cursor may be toggled on and off at the current cursor position by pressing Ctrl+R on the keyboard. Toggles a reference cursor on and off at the current cursor location on the graph.

Keyboard Shortcuts

There are a number of ways to enhance the analysis of spectral and other data using the keyboard or mouse clicks in conjunction with the keyboard. The following tables list all of the keyboard shortcuts available with the ALERT software.

The first table (below) shows shortcuts only available while in Graph View.

The second table shows general shortcuts that may be used in ALERT, regardless of whether you are in Detail View, List View, Graph View, Analysis View, or Photo/Drawing View.
The software will respond regardless of case (for example, both S and s will toggle the spectral graphs).
In all cases, a plus sign (+) shown between keys means the keys must be pressed simultaneously.
