Logged Data Window

The Logged Data window appears below the Project View in LabVIEW SignalExpress and displays a list of all logged data and snapshots from the current project sorted by the time at which you recorded the log or took the snapshot. You can use the Logged Data window to view, export, and manage logged data and snapshots.

When you create a new data log or snapshot, the name of the new data log or snapshot automatically appears in the Logged Data window. Expand the name to display the signals that the data log or snapshot contains.

Managing Logged Data

Each data log has a top-level, user-defined name. The default name is the timestamp, but you can right-click the timestamp and select Rename from the shortcut menu to rename a log.

Note  You also can use the Recording Options tab to name a log before you record the log.

The name of the active log appears in bold in the Logged Data window. Right-click the name of a data log and select Make Active Log to make that log the active log. If you are viewing a log on the Data View tab, the display updates to display the active log.

When you expand a data log in the Logged Data window, you can right-click a signal within the data log and select from the following shortcut menu options to manage the logged signal:

• Properties—Displays a summary of the properties of the logged signal.
• Show Alarms and Events—Displays a list of all the alarms and events in the logged signal.
• Open Folder—Navigates to the location of the logged signal on disk.
• Convert to ASCII—Converts the logged signal to an ASCII file.
• Export to Microsoft Excel—Exports the logged data to Microsoft Excel. This option exports every sample in the log.

Note  When you export data to Microsoft Excel, LabVIEW SignalExpress copies data samples to a clipboard for export. Use the Maximum Clipboard Data Export Size option on the Data page of the Options dialog box to increase the number of data samples the clipboard can contain.

• Open in DIAdem—Opens the logged signal in DIAdem.
• Make Log Viewable—Specifies for LabVIEW SignalExpress to process the log so you can view the log on a reasonable scale in a display on the Data View tab. Select this option if you set Prepare log data for viewing to Never on the Logging page of the Options dialog box.

Managing Snapshots

Each snapshot has a top-level, user-defined name. The default name is the timestamp, but you can right-click the timestamp and select Rename from the shortcut menu to rename a snapshot.

Note  You also can use the Create Snapshot dialog box to name a snapshot before you create the snapshot.

When you expand a snapshot in the Logged Data window, you can right-click a signal within the snapshot and select from the following shortcut menu options to manage the signal:

• Send To—Sends the signal to an analysis step.
• Probe—Displays a Data Probe window with detailed information about the signal.
• Copy Value—Copies the signal value as text that you can paste into a text file.
• Save Value—Saves the snapshot as a text file.
• Delete—Deletes the signal from the snapshot.
• Rename—Renames the signal.
