DAQ Plot ► Overview ► Export

DAQ Plot acquires data, but that is of limited value unless you can get that data to other applications or reports. The process of doing that is called Exporting. There are many ways to export data which are described in this section.

Export Menu Items

Save Channel Values...	Saves the actual data to a file. All data is saved according to the export settings in the Export Preferences.
Save Curve Values...	Saves the curve data values to a file. The curves are the current window curves, either the Signals or Spectra Curves. The spectra shows the full length of values while the signal values are clipped to the portion of the curve that is drawn.
Plot...	Sends either the Signal or Spectra Plot to Graph IDE depending upon which one is in the key window at the time. See the Graph IDE User Manual for further information.

The Channel Values output shows the data directly from the data buffer of DAQ Plot while the Curve Values output shows data which is represented by the curves shown on the respective window. As such, you can use the curve settings to clip the Curve Values in time and to output different spectral representations such as linear and DB.

Window Menu Items

Tables respond to copy and paste commands and are a good way to import and export data. To import data you should first make sure that data acquisition is off because otherwise importing will remove a segment of data between the time the table was updated to the time that the internal buffer flushed to the data repository.

Channel Values...	Shows the actual data in a table. Components of the table can be selected and copied according to the table processing described in the Graph IDE User Manual. Withe the Pro version of DAQ Plot, data can also be edited via the Channel table.
Curve Values...	Shows the curve data values in a table. The curves are the current window curves, either the Signals or Spectra Curves. The spectra shows the full length of values while the signal values are clipped to the portion of the curve that is drawn. Components of the table can be selected and copied according to the table processing described in the Graph IDE User Manual

File Menu Items

Use the import and export file menu items to import and export data from and to files. This operates via the table interface.

Before importing data make sure to set the Export Preferences Seconds format correctly, either Relative, Absolute or Date. This corresponds to the first column in the channel table and is what queues the interpretation of that column. Also, set the device type in the Main Preferences to None so that DAQ Plot does not attempt to acquire data upon launch.

Save Data...	Use this to save a binary representation of the current data. The file type is vvisignals which is recognized by DAQ Plot as a data store so double clicking such a file within the Finder will load the data within DAQ Plot.
Open Data...	Use this to open a file previously saved using the Save Data menu item.
Import To Channel Table...	Use this to import a file to the channel table and hence to the data repository within DAQ Plot. Table importing is described in the Graph IDE User Manual. Importing is only available with the Pro version.
Export From Channel Table...	Use this to export channel table data and hence the data repository to an external file. Table exporting is described in the Graph IDE User Manual.

Stdout

Use the stdout option in the Export Preferences to output to stdout (many times the console). Extra feature: If you run DAQ Plot at the command line then you can redirect stdout to a file or another process using standard unix methodology.

Backup

Use Decoding Backup to export to another process while at the same time running DAQ Plot, or to efficiently and automatically post-process data directly from the backup files.

Format

The export plain text format is tab delimited list of columns and rows. Each column is optional and defined by the Export Preferences. Each row is one time-sample worth of data:

Index Second Channel-1 Channel-2 ... Channel-16
...
Index Second Channel-1 Channel-2 ... Channel-16
