Create a trend session

Use trace data in a trend session to monitor assets, anticipate problems, and proactively perform preventative maintenance.

To create a trending session:

1. In the left pane, select Visualization > Trend.

2. In the Add Traces pane, select the Assets or Streams tab.

   Note: Communities are only available for selection from the Streams tab.

3. Add one or more traces to the trend session.

   To search for a trace, enter the asset name, stream name, or description in the Enter search query field. For more information on other ways to query, see Search queries. When adding asset traces (but not stream traces), the search field includes autocomplete functionality.

   After you find the traces that you want, select the Add icon to add them to the Trend.

   When you finish adding traces, select the Close icon in the Add Traces pane to hide the pane and maximize the available area to display the trend session.

4. From the Change Y-axis Mode menu, select a view:

   Trend View	Icon	Description
   Single mode		All traces display with the same scale on the same trend.
   Multiple mode		Each trace displays with its own scale and all traces are on the same trend.
   Stacked mode		Each measurement plots on its own trend.

5. From the Time picker, select the time range to view.

   • Select the Quick Ranges tab to choose a predefined time range.

   • Select the Custom Range tab to choose your own time range.

     

6. Select Step backward or Step forward to move the time range of the data displayed in the trend session.

   The trace will move in time increments displayed in the time range picker. For example, if the trend session displays the last 8 hours, Step backward shows the previous 8-hour period. If it displays the last 30 days, Step forward shows the next 30-day period. Select the triangle to select another time range or specify a custom range.

   The Trend legend displays the Trend view . It shows the legend for each trace, the last value, minimum, maximum, and average values in the displayed time range.

7. From the legend table, select a trace to view it for further analysis.

   The selected trace is highlighted and two cursors automatically mark the minimum and maximum values for the displayed time range. These cursors, called easy cursors, remain as long as the trace is highlighted.

   

8. Select the Add icon above the trace to lock the cursors in place.

   The Add icon turns into a Close icon. To unlock the cursor, select the Close icon.

   Note: When two cursors are locked, the Trend legend displays summary calculations for the values between the two cursors, known as the Cursor view .

9. Select the Share icon in the menu bar to copy the URL of the trend session.

   You can share this URL with colleagues to give them the same view of the trend session that they can use to troubleshoot problems.
