Graphing Digital Data

Complete the following steps to display a digital signal in a digital waveform graph.

  1. Acquire a digital signal. Refer to Chapter 8, Digital I/O, in the LabVIEW Measurements Manual for information about acquiring digital signals.
  2. Build a front panel with the following objects:
  3. Select the Bundle function located on the Functions»Cluster palette, and place it on the block diagram.
  4. Expand it to include four inputs and label the Bundle node Digital Graph Bundle.
  5. Wire the front panel objects to the Bundle inputs in the following order:
    1. Wire X0 to the first (top) input.
    2. Wire dx to the second input.
    3. Wire the digital signal to the third input.
    4. Wire Ports to the fourth (bottom) input.
  6. Wire the resulting output cluster of the Bundle function to the digital waveform graph. You also can mask the digital data.
  7. Run the VI.

Refer to the Simple Digital Waveform Graph VI in the examples\general\graphs\DigitalWaveformGraph.llb for an example of graphing digital data.
