Summary:	This article explains how to configure and user viewers to analyze data from sensors and trends in features calculated from sensor data.

Viewers contain charts in which you analyze data from sensors as well as trends in features calculated from sensor data.

For example, Waveform is sensor data of acceleration values from an accelerometer, and the RMS value is a feature for which you can calculate trends from the waveform. The workspace provides viewers for both waveform and trend data.

Trend viewer—Displays trends in features over time. The workspace always contains a single Trend viewer in the top row.
Sensor data viewers—Display raw sensor data as waveforms, spectrums, orbits, and other sensor data types. The workspace can contain as many or as few sensor data viewers as you want.

Relationship Between Feature Trends and Sensor Data

Note

The peak may not be a point represented on the graph because it may fall between two recorded points.

The callout numbers on the following workspace show the relationship between sensor data and trends.

	Feature trend values—Represent the feature values from acquisitions over time.
	Cursor within trend curve—Controls which data set appears in sensor data viewers.
	Sensor data—Represents the data set where the Trend viewer cursor lies.

Adding Harmonic and Sideband Cursors to Viewers

Ensure you are on the Data Viewer page by clicking the Data Viewer button.

You can enable harmonic or sideband cursor indicators in spectrum viewers. Harmonic and sideband cursors are particularly useful in analyzing and diagnosing spectrums.

To add harmonic or sideband cursors to a viewer, click the Cursor button on the viewer toolbar and select Harmonic or Sideband, then click the point on the chart where you want to place the cursor.

You can reposition the cursors by double-clicking another point on the chart, or by single-clicking the sideband or harmonic you want to select.

The pull-down menu for the Cursor button () on the viewer toolbar contains the following options.

Normal—Displays only the fundamental cursor in the viewer.
Harmonic—Displays cursors to the right of the fundamental cursor at fixed intervals that are integer multiples of the x-axis value of the fundamental cursor. For example, when the fundamental cursor is at 100 Hz, the first harmonic cursor will be at 200 Hz, the second at 300 Hz, the third at 400 Hz, and so on.
Sideband—Displays cursors at fixed intervals on the left and on the right side of the fundamental cursor.
Change the number of harmonic and sideband cursors.
1. To change the number of cursor lines that display when you enable the harmonic or sideband cursor, click the Settings button on one of the viewer toolbars and select Viewer Settings .
2. Specify the numbers you want in the resulting dialog box.
3. Click OK.

Adding, Changing, and Removing Viewers

Customize the workspace by adding, removing, or changing the types of viewers in the workspace.

If you create a layout you want to reuse, you can save that layout and restore it later. When you exit the Data Viewer page or switch modes, the workspace does not preserve your changes to the layout unless you save the layout.

Complete the following steps to add a new viewer to the workspace.

Click the Data Viewer () button.
Click the Layout menu in the top right-hand corner of the Data workspace.
Click New Row to add an empty row to the bottom of the workspace.
Click Add Chart and choose which row you want to add your viewer to. The Data Viewer page adds an empty area at the row you selected. The Trend viewer is always the left-most viewer in the top row.
Change the type and size of a viewer.
- Viewer Type—Click the Layout menu in the toolbar for any viewer except the Trend viewer and select Chart type > Type.
  
  Note
  
  You cannot change the Trend viewer to a different viewer type.
- Size—Hover over and drag the separating bars around any area, including the asset tree and properties pane.
Remove rows and charts.
- To remove any viewer except the Trend viewer, click the Layout menu on the viewer toolbar and select Remove this chart.
- To remove an entire row of viewers, click the Layout menu on a viewer toolbar and select Remove entire row.
  
  Note
  
  The Trend viewer is always visible, and you cannot remove it from the workspace.

Stacking Charts in the Same Viewer

Stack multiple charts in the same viewer.

Some viewers can display plots in separate, stacked charts within the same viewer. Complete the following steps to stack multiple charts in the same viewer.

Click the Data Viewer () button.
In the asset tree, <Ctrl-click> or <Shift-click> multiple features to load them in the viewers.
Click the Stacked Charts () button on the viewer toolbar.
Click the Normalize Y-Axis Scales button on the viewer toolbar to give each separate chart the same y-axis values.

Modifying Default Units and Scaling for Data

Click the Navigation menu () and select Options.
In the resulting dialog box, select Units and Scaling under the Data Viewer section in the navigation pane.
You can do the following.
- Change the units to integrate and differentiate.
- Specify the default value for Single Integration Cutoff and Double Integration Cutoff.
- Change the acceleration, velocity, and displacement scaling for Spectrum, Full Spectrum, and Waterfall viewers.
